I have ASCAT v3.1.2 and have the issue
[1] Plotting tumor data
[1] Sample S1 (1/100)
Error in !is.null(homsegs) && !is.na(homsegs) :
'length = 6' in coercion to 'logical(1)'

Hi, "homsegs" is the germline homozygous stretches. The error message indicates that no any homo segments was detected. Do you have normal control or you run the tumor only mode? You may need to check your normal sample.

Hi @mital14,

This issue seems related to newer versions of R (4.3.0+) where arguments around the && operator must have the same lengths. A fix has been implemented as part of ASCAT v3.1.2 (c4c10f8) but we did not create a specific release for it. In your case, you must be using a v3.1.2 prior to this fix so installing a newer version of ASCAT (devtools::install_github('VanLoo-lab/ascat/ASCAT')) should fix your issue.

@zhangzhhcb: this dataset (S1 (1/100)) corresponds to the example dataset of 100 samples we provide here.

Cheers,

Tom.
