Currently, the package can\nread OPUS data files and communicate/control OPUS software using the DDE communication protocol)
\n\n
Installation
\n\n
brukeropus requires python 3.6+ and numpy, but matplotlib is needed to run the plotting examples.  You can\ninstall with pip:
\n\n
\n
pip install brukeropus\n
\n
\n\n
Namespace
\n\n
brukeropus provides direct imports to the following:
\n\n
\n
from brukeropus import find_opus_files, read_opus, OPUSFile, Opus\n
\n
\n\n
All other file functions or classes can be directly imported from the brukeropus.file or brukeropus.control\nsubmodules, e.g.:
\n\n
\n
from brukeropus.file import parse_file_and_print\n
\n
\n\n
It is recommended that you do not import from the fully qualified namespace, e.g.:
\n\n
\n
from brukeropus.file.utils import parse_file_and_print\n
\n
\n\n
as that namespace is subject to change. Instead import directly from brukeropus or its first level submodules.
\n\n
Reading OPUS Files (Basic Usage)
\n\n
\n
from brukeropus import read_opus\nfrom matplotlib import pyplot as plt\n\nopus_file = read_opus('file.0')  # Returns an OPUSFile class\n\nopus_file.print_parameters()  # Pretty prints all metadata in the file to the console\n\nif 'a' in opus_file.data_keys:  # If absorbance spectra was extracted from file\n    plt.plot(opus_file.a.x, opus_file.a.y)  # Plot absorbance spectra\n    plt.title(opus_file.sfm + ' - ' + opus_file.snm)  # Sets plot title to Sample Form - Sample Name\n    plt.show()  # Display plot\n
\n
\n\n
More detailed documentation on the file submodule can be found in brukeropus.file
\n\n
Controlling OPUS Software (Basic Usage)
\n\n
\n

The brukeropus.control submodule of brukeropus includes the Opus class for communicating with OPUS software. The\nOpus class currently supports communication through the Dynamic Data Exchange (DDE) protocol.  This class can be used\nto script measurement sweeps and perform various low-level operations (e.g. move mirrors, rotate polarizers, etc.). In\norder to communicate with OPUS, the software must be open, logged in, and running on the same PC as brukeropus.
\n\n
Initializing/verifying connection to OPUS Software
\n\n
\n
from brukeropus import Opus\n\nopus = Opus()  # initialization of class automatically connects to open OPUS software\nprint(opus.get_version())  # prints the current OPUS software version\n
\n
\n\n
Get information about a parameter (e.g. DTC, APT, VEL).
\n\n
\n
opus = Opus()\nparam = 'vel'\nprint(opus.get_param_label(param))\nprint(opus.get_param_options(param))\n

The brukeropus.file submodule of brukeropus includes all the functions and classes for reading and exploring OPUS\nfiles. This includes both high-level functions like read_opus that returns an OPUSFile class, as well as low-level\nparsing functions like parse_directory that returns data extracted directly from the binary OPUS file bytes.  This\noverview documentation will focus on the high-level functions which will be useful for most users.  If you are\ninterested in using the low-level parsing functions, perhaps to make your own data class or customize how files are\nread, refer to: brukeropus.file.parser which contains all the low-level parsing functions.
\n\n
Finding OPUS Files
\n\n
OPUS files are typically saved with a numeric file extension (e.g. file.0, file.1, file.1001).  This makes searching for\na list of OPUS files in a directory a little more cumbersome than a traditional \"*.csv\" search.  To address this,\nbrukeropus includes a find_opus_files function:
\n\n
\n
from brukeropus import find_opus_files\n\nfilepaths = find_opus_files(r'path\\to\\opus\\files', recursive=True)\n
\n
\n\n
Which will assign a list of filepaths that match the numeric extension formatting of OPUS files. For full documentation,\nsee brukeropus.file.utils.find_opus_files.
\n\n
Reading OPUS Files
\n\n
brukeropus parses OPUS files and assembles them into an OPUSFile object that contains the extracted data (and\nmetadata) within the file.  You can generate an OPUSFile object in one of two ways:
\n\n
\n
from brukeropus import read_opus, OPUSFile\n\nfilepath = r'path\\to\\opusfile.0'\n\ndata = read_opus(filepath)\nsame_data = OPUSFile(filepath)\n
\n
\n\n
In the above code, data and same_data are both OPUSFile objects with identical data.
\n\n
Using the OPUSFile Class
\n\n
OPUS files all start with the same first four magic bytes.  If the file does not start with these bytes (i.e. is not\na valid OPUS file), the OPUSFile class will logically evaluate to false:
\n\n
\n
data = read_opus('file.pdf')\nif data:\n    print(data)\nelse:\n    print(data.filepath, 'is not an OPUS file')\n
\n
\n\n
To view all parameter metadata in the file, you can print to the console using the class method: print_parameters.\nThis will let you view all the key, value parameter data extracted from the file with labels for what the parameter keys\nare referring to wherever known.
\n\n
\n
data = read_opus('file.0')\ndata.print_parameters()\n
\n
\n\n
\nExample print_parameters Output

You can access a specific parameter simply by calling the key as a direct attribute of the class (case insensitive). You\ncan also get the human-readable label using the get_param_label function:
\n\n
\n
from brukeropus.file import get_param_label\ndata = read_opus('file.0')\nprint(get_param_label('bms') + ':', data.bms)\nprint(get_param_label('src') + ':', data.src)\n
\n
\n\n
\n
Beamsplitter: KBr-Broadband\nSource: MIR\n
\n
\n\n
You will notice in the example output that some keys (e.g. zero filling factor zff) may have two entries: one for the\nsample measurement and another for the reference.  By default, the sample parameters are accessible directly from the\nOPUSFile class, while the reference parameters can be accessed through the rf_params attribute.
\n\n
\n
data = read_opus('file.0')\nprint('Sample ZFF:', data.zff, 'Reference ZFF:', data.rf_params.zff)\n
\n
\n\n
\n
Sample ZFF: 2 Reference ZFF: 2\n
\n
\n\n
You can also iterate over the parameters using the familiar keys(), values(), and items() functions using the\nparams or rf_params attributes:
\n\n
\n
data = read_opus('file.0')\nfor key, val in data.params.items():\n    print(key + ':', val)\n
\n
\n\n
\n

\n
\n\n
Depending on the settings used to save the OPUS file, different data blocks can be stored.  To retrieve a list of data\nblocks stored in the OPUS File, use the data_keys attribute:
\n\n
\n
data = read_opus('file.0')\nprint(data.data_keys)\n
\n
\n\n
\n
['igsm', 'phsm', 'sm', 'a', 'igrf', 'rf']\n
\n
\n\n
Each key is also an attribute of the OPUSFile instance that returns either a Data or Data3D class.  You can get\nthe x and y array values (in the units they were saved in) as direct attributes to the Data class:
\n\n
\n
data = read_opus('file.0')\nplt.plot(data.a.x, data.a.y)\nplt.ylim((0, 1))\nplt.show()\n
\n
\n\n
For spectra with wavenumber as valid unit (e.g. single-channel or ratioed spectra), the x array can be given in cm\u207b\u00b9\nor \u00b5m units by using the attributes wn or wl respectively:
\n\n
\n
data = read_opus('file.0')\nplt.plot(data.sm.wl, data.sm.y)\nplt.show()\n
\n
\n\n
You can also iterate over all data spectra in the file using the iter_data() method:
\n\n
\n
data = read_opus('file.0')\nfor d in data.iter_data():\n    print(d.label, '(' + d.datetime.isoformat(' ') + ')')\n
\n
\n\n
\n

\n
\n\n
Each data block in an OPUS file also contains a small parameter block with information such as the min/max y-value\n(mny, mxy), x-units (dxu), number of data points (npt), etc.  These can be accessed as direct attributes to the Data\nclass, or through the params attribute:
\n\n
\n
data = read_opus('file.0')\nprint('Sample spectra y-min:', data.sm.mny, 'y-max:', data.sm.mxy)\n
\n
\n\n
\n
Sample spectra y-min: 1.2147593224653974e-05 y-max: 0.03543896973133087\n

Class containing parameter metadata of an OPUS file.
\n\n
Parameters of an OPUS file are stored as key, val pairs, where the key is always three chars.  For example, the\nbeamsplitter is stored in the \"bms\" attribute, source in \"src\" etc.  A list of known keys, with friendly label can\nbe found in brukeropus.file.constants.PARAM_LABELS.  The keys in an OPUS file are not case sensitive, and stored\nin all CAPS (i.e. BMS, SRC, etc.) but this class uses lower case keys to follow python convention.  The class is\ninitialized from a list of parameter FileBlockInfo.  The key, val items in blocks of the list are combined into\none parameter class, so care must be taken not to pass blocks that will overwrite each others keys.  Analagous to a\ndict, the keys, values, and (key, val) can be iterated over using the functions: keys(), values(), and items()\nrespectively.

Contains type and pointer information for all blocks of data in an OPUS file.
\n\n
FileDirectory information is decoded from the raw file bytes of an OPUS file. First the header is read which\nprovides the start location of the directory block, number of blocks in file, and maximum number of blocks the file\nsupports. Then it decodes the block pointer information from each entry of the file's directory block. Rather than\nstore all file blocks in a single list (as it is done in the OPUS file directory), this class sorts the blocks into\ncategories: data, data_status, params, rf_params, directory, and file_log.  It also pairs the data\nblocks with their corresponding data_status block to simplify grouping y data with the parameters that are used to\ngenerate x data and other data block specific metadata.

Parses directory block of OPUS file and yields block info for all blocks in the file as a generator.
\n\n
The directory block of an OPUS file contains information about every block in the file. The block information is\nstored as three int32 values: type_int, size_int, start.  type_int is an integer representation of the block\ntype. The bits of this type_int have meaning and are parsed into a tuple using get_block_type. The size_int is\nthe size of the block in 32-bit words. start is the starting location of the block (in number of bytes).

Parses the bytes in a data block (specified by size and start pointers) and returns a numpy array.
\n\n
Data blocks contain no metadata, only the y-values of a data array. Data arrays include: single-channel sample,\nreference, phase, interferograms, and a variety of resultant data (transmission, absorption, etc.).  Every data\nblock should have a corresponding data status parameter block which can be used to generate the x-array values for\nthe data block. The data status block also specifies the data type of the data array with the DPF parameter. It\nappears that OPUS currently exclusively stores data blocks as 32-bit floats, but has a reservation for 32-bit\nintegers when DPF = 2.

brukeropus is a Python package for interacting with Bruker's OPUS spectroscopy software. Currently, the package can\nread OPUS data files and communicate/control OPUS software using the DDE communication protocol)
\n\n
Installation
\n\n
brukeropus requires python 3.6+ and numpy, but matplotlib is needed to run the plotting examples.  You can\ninstall with pip:
\n\n
\n
pip install brukeropus\n
\n
\n\n
Namespace
\n\n
brukeropus provides direct imports to the following:
\n\n
\n
from brukeropus import find_opus_files, read_opus, OPUSFile, Opus\n
\n
\n\n
All other file functions or classes can be directly imported from the brukeropus.file or brukeropus.control\nsubmodules, e.g.:
\n\n
\n
from brukeropus.file import parse_file_and_print\n
\n
\n\n
It is recommended that you do not import from the fully qualified namespace, e.g.:
\n\n
\n
from brukeropus.file.utils import parse_file_and_print\n
\n
\n\n
as that namespace is subject to change. Instead import directly from brukeropus or its first level submodules.
\n\n
Reading OPUS Files (Basic Usage)
\n\n
\n
from brukeropus import read_opus\nfrom matplotlib import pyplot as plt\n\nopus_file = read_opus('file.0')  # Returns an OPUSFile class\n\nopus_file.print_parameters()  # Pretty prints all metadata in the file to the console\n\nif 'a' in opus_file.data_keys:  # If absorbance spectra was extracted from file\n    plt.plot(opus_file.a.x, opus_file.a.y)  # Plot absorbance spectra\n    plt.title(opus_file.sfm + ' - ' + opus_file.snm)  # Sets plot title to Sample Form - Sample Name\n    plt.show()  # Display plot\n
\n

The brukeropus.control submodule of brukeropus includes the Opus class for communicating with OPUS software. The\nOpus class currently supports communication through the Dynamic Data Exchange (DDE) protocol.  This class can be used\nto script measurement sweeps and perform various low-level operations (e.g. move mirrors, rotate polarizers, etc.). In\norder to communicate with OPUS, the software must be open, logged in, and running on the same PC as brukeropus.
\n\n
Initializing/verifying connection to OPUS Software
\n\n
\n
from brukeropus import Opus\n\nopus = Opus()  # initialization of class automatically connects to open OPUS software\nprint(opus.get_version())  # prints the current OPUS software version\n

The brukeropus.file submodule of brukeropus includes all the functions and classes for reading and exploring OPUS\nfiles. This includes both high-level functions like read_opus that returns an OPUSFile class, as well as low-level\nparsing functions like parse_directory that returns data extracted directly from the binary OPUS file bytes.  This\noverview documentation will focus on the high-level functions which will be useful for most users.  If you are\ninterested in using the low-level parsing functions, perhaps to make your own data class or customize how files are\nread, refer to: brukeropus.file.parser which contains all the low-level parsing functions.
\n\n
Finding OPUS Files
\n\n
OPUS files are typically saved with a numeric file extension (e.g. file.0, file.1, file.1001).  This makes searching for\na list of OPUS files in a directory a little more cumbersome than a traditional \"*.csv\" search.  To address this,\nbrukeropus includes a find_opus_files function:
\n\n
\n
from brukeropus import find_opus_files\n\nfilepaths = find_opus_files(r'path\\to\\opus\\files', recursive=True)\n
\n
\n\n
Which will assign a list of filepaths that match the numeric extension formatting of OPUS files. For full documentation,\nsee brukeropus.file.utils.find_opus_files.
\n\n
Reading OPUS Files
\n\n
brukeropus parses OPUS files and assembles them into an OPUSFile object that contains the extracted data (and\nmetadata) within the file.  You can generate an OPUSFile object in one of two ways:
\n\n
\n
from brukeropus import read_opus, OPUSFile\n\nfilepath = r'path\\to\\opusfile.0'\n\ndata = read_opus(filepath)\nsame_data = OPUSFile(filepath)\n
\n
\n\n
In the above code, data and same_data are both OPUSFile objects with identical data.
\n\n
Using the OPUSFile Class
\n\n
OPUS files all start with the same first four magic bytes.  If the file does not start with these bytes (i.e. is not\na valid OPUS file), the OPUSFile class will logically evaluate to false:
\n\n
\n
data = read_opus('file.pdf')\nif data:\n    print(data)\nelse:\n    print(data.filepath, 'is not an OPUS file')\n
\n
\n\n
To view all parameter metadata in the file, you can print to the console using the class method: print_parameters.\nThis will let you view all the key, value parameter data extracted from the file with labels for what the parameter keys\nare referring to wherever known.
\n\n
\n
data = read_opus('file.0')\ndata.print_parameters()\n
\n

You can access a specific parameter simply by calling the key as a direct attribute of the class (case insensitive). You\ncan also get the human-readable label using the get_param_label function:
\n\n
\n
from brukeropus.file import get_param_label\ndata = read_opus('file.0')\nprint(get_param_label('bms') + ':', data.bms)\nprint(get_param_label('src') + ':', data.src)\n
\n
\n\n
\n
Beamsplitter: KBr-Broadband\nSource: MIR\n
\n
\n\n
You will notice in the example output that some keys (e.g. zero filling factor zff) may have two entries: one for the\nsample measurement and another for the reference.  By default, the sample parameters are accessible directly from the\nOPUSFile class, while the reference parameters can be accessed through the rf_params attribute.
\n\n
\n
data = read_opus('file.0')\nprint('Sample ZFF:', data.zff, 'Reference ZFF:', data.rf_params.zff)\n
\n
\n\n
\n
Sample ZFF: 2 Reference ZFF: 2\n
\n
\n\n
You can also iterate over the parameters using the familiar keys(), values(), and items() functions using the\nparams or rf_params attributes:
\n\n
\n
data = read_opus('file.0')\nfor key, val in data.params.items():\n    print(key + ':', val)\n

\n
\n\n
Depending on the settings used to save the OPUS file, different data blocks can be stored.  To retrieve a list of data\nblocks stored in the OPUS File, use the data_keys attribute:
\n\n
\n
data = read_opus('file.0')\nprint(data.data_keys)\n
\n
\n\n
\n
['igsm', 'phsm', 'sm', 'a', 'igrf', 'rf']\n
\n
\n\n
Each key is also an attribute of the OPUSFile instance that returns either a Data or Data3D class.  You can get\nthe x and y array values (in the units they were saved in) as direct attributes to the Data class:
\n\n
\n
data = read_opus('file.0')\nplt.plot(data.a.x, data.a.y)\nplt.ylim((0, 1))\nplt.show()\n

For spectra with wavenumber as valid unit (e.g. single-channel or ratioed spectra), the x array can be given in cm\u207b\u00b9\nor \u00b5m units by using the attributes wn or wl respectively:
\n\n
\n
data = read_opus('file.0')\nplt.plot(data.sm.wl, data.sm.y)\nplt.show()\n
\n
\n\n
You can also iterate over all data spectra in the file using the iter_data() method:
\n\n
\n
data = read_opus('file.0')\nfor d in data.iter_data():\n    print(d.label, '(' + d.datetime.isoformat(' ') + ')')\n
\n
\n\n

Sample Interferogram (2019-05-03 13:34:44.641000)\nSample Phase (2019-05-03 13:34:44.641000)\nSample Spectrum (2019-05-03 13:34:44.641000)\nAbsorbance (2019-05-03 13:34:44.641000)\nReference Interferogram (2019-05-03 13:31:22.358000)\nReference Spectrum (2019-05-03 13:31:22.358000)\n
\n
\n\n
Each data block in an OPUS file also contains a small parameter block with information such as the min/max y-value\n(mny, mxy), x-units (dxu), number of data points (npt), etc.  These can be accessed as direct attributes to the Data\nclass, or through the params attribute:
\n\n
\n
data = read_opus('file.0')\nprint('Sample spectra y-min:', data.sm.mny, 'y-max:', data.sm.mxy)\n
\n
\n\n
\n
Sample spectra y-min: 1.2147593224653974e-05 y-max: 0.03543896973133087\n

Class containing parameter metadata of an OPUS file.
\n\n
Parameters of an OPUS file are stored as key, val pairs, where the key is always three chars.  For example, the\nbeamsplitter is stored in the \"bms\" attribute, source in \"src\" etc.  A list of known keys, with friendly label can\nbe found in brukeropus.file.constants.PARAM_LABELS.  The keys in an OPUS file are not case sensitive, and stored\nin all CAPS (i.e. BMS, SRC, etc.) but this class uses lower case keys to follow python convention.  The class is\ninitialized from a list of parameter FileBlockInfo.  The key, val items in blocks of the list are combined into\none parameter class, so care must be taken not to pass blocks that will overwrite each others keys.  Analagous to a\ndict, the keys, values, and (key, val) can be iterated over using the functions: keys(), values(), and items()\nrespectively.

Contains type and pointer information for all blocks of data in an OPUS file.
\n\n
FileDirectory information is decoded from the raw file bytes of an OPUS file. First the header is read which\nprovides the start location of the directory block, number of blocks in file, and maximum number of blocks the file\nsupports. Then it decodes the block pointer information from each entry of the file's directory block. Rather than\nstore all file blocks in a single list (as it is done in the OPUS file directory), this class sorts the blocks into\ncategories: data, data_status, params, rf_params, directory, and file_log.  It also pairs the data\nblocks with their corresponding data_status block to simplify grouping y data with the parameters that are used to\ngenerate x data and other data block specific metadata.

Returns a short but descriptive label for 3-letter parameters. For example, bms returns Beamsplitter.
\n\n
The 3-letter parameter input is not case sensitive.  This package includes the majority of parameters that OPUS\nuses, but in the event a parameter label is not known, this function will return: \"Unknown XXX\" where XXX is the\nunknown 3-letter parameter.
\n\n
Arguments:
\n\n
    \n
  • param:  three letter parameter code (e.g. bms, src, npt, etc.) [not case sensitive]

Returns the type code label of a file block given the position index and value of the type code.
\n\n
The file blocks on an OPUS file feature six-integer type codes, for example (3, 1, 1, 2, 0, 0), that categorize the\ncontents of the file block. The positional index defines the category, while the value at that index defines the\nspecific type of that category.  For example, the first integer (pos_idx=0), describes the type of data in the\nblock, if applicable:
\n\n
0: Undefined or N/A,\n1: Real Part of Complex Data,\n2: Imaginary Part of Complex Data,\n3: Amplitude\n
\n\n
This package includes the majority of type codes that OPUS uses, but in the event a type code label is not known,\nthis function will return: \"Unknown 0 4\" where the first number is the position index, and the second is the\nunknown value integer.
\n\n
Arguments:
\n\n
    \n
  • pos_idx:  positional index of the type code (0 - 5)
    • \n
  • val:  value of the type code

Returns a shorthand key for a given data block type: sm, rf, igsm, a, t, r, etc.
\n\n
Determines if the data block type is an interferogram, single-channel, absorption, etc. and whether it is associated\nwith the sample or reference channel and returns a shortand key-like label: sm, rf, igsm, igrf, a, t, r, etc.  For\nthe full data label (e.g. Sample Spectrum, Absorbance) use: get_block_type_label.\nThis package includes the majority of type codes that OPUS uses, but in the event a type code label is not known,\nthis function will return: \"_33\" or \"sm_33\" where 33 will change to the unkown block_type integer value.
