Hello!
I would like to retrieve data from copy number variants for all cell lines. The most important information for me is the absolute copy number of minor and major alleles for a given segment. I found such a file in the current release (OmicsAbsoluteCNSegmentsProfile.csv), but unfortunately after downloading it I get a different file. The difference is not big - instead of the MajorAlleAbsoluteCN column there is a SegmentAbslouteCN column.
Of course, I should be able to calculate the absolute number of major alleles, but there are a lot of floating point values in SegmentAbsolutreCN and I’m not sure how to interpret them.
Moreover, in the second file named OmicsCNSegmentsProfile.csv there is a completely different number of variants and not all of them correspond to the first file.
Is this some kind of error in the files?
Thank you for any help!
