    Where can we find a description on what all of the outputs of the somatic copy number pipeline are?

    In particular we want to know what each of these seg files are:

    allele_fraction_legacy_segments_tumor
    called_copy_ratio_legacy_segments_tumor
    called_copy_ratio_segments_tumor
    copy_ratio_legacy_segments_tumor
    copy_ratio_only_segments_tumor
    modeled_segments_begin_tumor
    modeled_segments_tumor
