group_by function error

[Taekya]

Hello, An error occurred when executing the function as shown below.
group_by function error occurs in the run_2 step after the run_1 step is completed.
When executing the code manually, an error occurred CNAqc::init(snvs = mutations, cna = fits$segments, purity = fits$purity, ref = reference) %>% analyze_peaks().
group_by error occurred when executing the x$peaks_analysis$general$analysis = analysis script when executing analyze_peaks_common function in analyze_peaks function.
how to fix this error?

Hi, I pass this along to @nicola-calonaci since he developed Sequenza_CNAqc. As gut feeling I am afraid it crashes because there are no simple CNAs in this sample - a trivial bug to fix. Is there any way you can share a dummy version of your object CNAqc::init(snvs = mutations, cna = fits$segments, purity = fits$purity, ref = reference) so that we can reproduce the bug?

I will close this issue since there was no reply from @Taekya.
