if clonal_frequency corresponds to purity / abberrant cell fraction from ascat

[ChelseaCHENX]

Hi there!

My question is basically the title - for the column of clonal frequency in allele-specific copy number data of input, is this equivalent to purity / abberrant cell fraction from ascat (eg, in output, one sample is assigned with one number of purity / abberrant cell fraction for all segments)?

Asking as we don't have direct allele-specific copy number from sequencing but only deduction from ascat. Wondering if we can proceed using ascat.

Thank you very much!!
