Alleles reported as numbers rather than bases in output VCF

[alexpiper]

Hi,

I am attempting to use GangSTR-2.5.0 and ive encountered a strange issue where the REF and ALT alelles in the output VCF are being reported as numbers rather than bases. i.e. CHROM POS ID REF ALT contig_1556 733473 . 7.57.57.57.57.57.57.5 7.57.57.57.57.5 contig_1794 304015 . 16161616161616161616161616161616 161616

This is the same for the repeat motif info field as well, for example for the above 2 positions: RU=7.5 RU=16

Any suggestions on what might be causing this and how to get around it?

Cheers, Alex
