-T CombineVariants ##### ERROR MESSAGE: For input string: "20"

Hello,

I called variants in chunks (100000 bp chunks) on chromosome 20 on 450 reduced BAMS using -T UnifiedGenotyper, which resulted in the generation of 631 VCFs.

Now I want to combine these 631 VCFs using -T CombineVariants, however there seems to be a problem with some of the VCFs and all I get is an error message.

I can combine the 5 first VCFs that were generated, but when I add a sixth one (chr20:400000_500000) I get the following error:

##### ERROR MESSAGE: For input string: "20"

If I exclude that file, I can combine about 30 VCFs until I encounter a similar error message for a different VCF file:

##### ERROR MESSAGE: For input string: "120"

I've looked through both of the "problematic" VCFs and can't see how they differ from the ones that I can combine.

Any idea of what may be going wrong and how I can solve this? At the moment I can only identify problematic VCF by trying to combine them using CombineVariants since I don't know what it is about these particular VCF files that is causing the problem.

Thanks for your help, Tota
