Launch BISCUT_preprocessing.py fails: issue with input

[kokonech]

Hi! I tried to run on CNV profiles from methylation data, but BISCUIT failed. Main error was the following:

Traceback (most recent call last):
  File "/b06x-isilon/b06x-m/mb/analysis/medullo/okonechn/BISCUT-py3-main/BISCUT_preprocessing.py", line 256, in <module>
    take_care_arms(tumor_type, date_suffix)
  File "/b06x-isilon/b06x-m/mb/analysis/medullo/okonechn/BISCUT-py3-main/BISCUT_preprocessing.py", line 251, in take_care_arms
    result.get(9999999)
  File "/b06x-isi/share/csw/15.x/x86_64_generic/software/Python/3.10.4-GCCcore-11.3.0/lib/python3.10/multiprocessing/pool.py", line 771, in get
    raise self._value
KeyError: 'start'

I only edited tumor_type, seg_file_suffix and date_suffix. Setting amplitude_threshold to 0.1 also did not help, even though distribution of Segment_mean is from -0.6 to 0.6. Here's the head of the CNV profile file collected from methylation data:

Sample	Chromosome	Start	End	Num_Probes	Segment_Mean
ICGC_MB305	1	521369	750000	10	0.011
ICGC_MB305	1	750001	800000	10	-0.037
ICGC_MB305	1	800001	850000	10	-0.033

ICGC_MB305	1	950001	1000000	10	0.044
...

What could be the problem? Any suggestions how to fix this?

P.S. I followed the tutorial in documentation, it went well but initailly running the BISCUT_preprocessing.py required the input file to be located in the docs subfolder:
FileNotFoundError: [Errno 2] No such file or directory: 'docs/PANCAN_ISAR.seg.txt'

I found this is hard-coded there. Probably could be noted in documentation.
