Problem with chr X XTR and Non_par regions about mocha HOT 7 CLOSED

This is puzzling. I am trying to replicate this issue on my side. Can you show me the output of:

$ bcftools view -h $dir/$pfx.bcf | grep ^##contig 

I am guessing that maybe you have both X and chrX in your VCF, which would be very odd.

Thank you for your support, here is the output of the bcftools command :

Yeah, so what is going on is that the code assigns XTR to X and then nonPAR to chrX and there is a sanity check that alerts something is off. It is a good thing that you are getting an error, though likely not the error message you would have wanted. How did you end up with a VCF with both X and chrX? You seem to have some more serious issues in the pipeline that generated the input VCF.

My original vcf header does not contain the last part of contig lines (those ##contig=<ID=16>) only the first one <ID=chrNN>.

At some point I mu0st have changed from chrN to N to agree with the reference.
Damn, century 21 it looks like and we still don't have a normalized chromosome naming...
Should I just replace the original chrN in my header and remove the additional contig lines ??

Thanks.

You should not have both contig names, that for sure. You should have the contig names in the header that match the contig names used for the variants. MoChA is designed to be flexible, so you can use either the names with or without the chr prefix. But not both.

Hi,

finally it works, I had to remove the ##contig=<ID=XXX> entries and rename entries like
##contig=<ID=chr1,length=249250621> into ##contig=<ID=1,length=249250621> to match vcf records coordinates.

For now, I am runnnig MoCha without --input-stats, is it possible to find an example file or how to generate one ?
My only input file is a vcf from whole genome sequencing.

Anyway, thank you again for your support.

Also make sure that the input VCF and the --variants VCF use the same naming scheme. The --input-stats is optional and is used to input call_rate and computed_gender information. If you don't use it, MoChA will infer these two variables.
