UltraTrace

This is a tool for [currently] manual annotation of 2D UTI (Ultrasound Tongue Imaging) data.

You can have a look at our UltraFest IX presentation for some details on featureset and functionality as of October, 2020.

Installation

Linux (apt or dnf)

1. Download the UltraTrace source code, e.g. using git.
2. Run setup in the UltraTrace directory:

$ ./install.sh
$ python3 setup.py install

macOS

1. Install Homebrew.
2. Download the UltraTrace source code, e.g. using git.
3. Run setup in the UltraTrace directory:

$ python3 setup.py install

Windows

1. Install python3
2. Make sure you have pip
3. Install ffmpeg and add to PATH
4. Run setup.py

Use

$ python3 -m ultratrace /path/to/data

Data format

The minimum data required for UltraTrace to run is at least one ultrasound file and at least one audio file (supported formats listed below). Annotation files store timing of the ultrasound frames as well as any linguistic information of use (words, segments, etc.). Corresponding ultrasound, audio, and annotation files should have the same base name (everything except the extension), and may be symlinked or stored in subdirectories. (The naming convention for AAA-exported data is a little different.)

Supported data formats

• ultrasound: DICOM (.dicom, .dcm), AAA-exported scanline data (.ult)
• audio: .wav, .flac
• text alignment: .TextGrid
• traces/splines: native .json, old native .measurement, AAA-exported splines

Supported data access methods:

Reading DICOM data is supported in the following ways:

• Reading native pixel data directly
• Converting pixel data to PNG
• Reading from Philips scanline data

Alignment of audio and ultrasound frames supports the following methods:

• From native Philips timing data
• Generated from DICOM frametime (or framerate) specification
• Manual adjustment of alignment
• Stored in TextGrids (actively stores above methods this way; can read alignment previously stored this way)
• Future: auxiliary synchronisation data

Themes

The theme should just look right on Mac.

Setting the theme on linux

Use pip3 to install ttkthemes.

Add the following line to your ~/.Xresources file:

*TtkTheme: arc

You may select something other than clam for your theme. Currently, the main options are something like this: arc, plastik, clearlooks, elegance, radiance, equilux, black, smog, scidblue, etc. See the ttkthemes documentation for more information.

Otherwise it'll fall back to *TtkTheme, and if that's not specified in ~/.Xresources, it'll fall back to clam.
