Can't run GATK HaplotypeCaller set ploidy = 1

[Genomics101]

Greetings!

I have been attempting to call variants on a haploid genome using GATK HaplotypeCaller, however when I set ploidy = 1, I get an error:

ERROR ------------------------------------------------------------------------------------------
ERROR A GATK RUNTIME ERROR has occurred (version 3.2-2-gec30cee):

My arguments are set as follows:

-T HaplotypeCaller -R Ref.fa -I aln-pe_RG_sorted_dedup_realigned.bam -o aln-pe_RG_sorted_dedup_realigned_HC_ploidy1.vcf -ploidy 1 -maxAltAlleles 2

However it runs perfectly with ploidy = 2.

Any help is appreciated.

Did you try to run it with GATK 3.4 ?
