I am trying to run the convertf tool in AdmixTools, as I have successfully run before. I am getting an error (warning perhaps? Because it appears to run to completion..?) that "snp order check fail; snp list not order". I built the original vcf file using GatherVCFs in GATK4 (previously CatVariants, GATK3), gathering the snp-called (HaplotypeCaller command) files in the order they were generated in, then used vcftoolsto output ped/map format files.

My command:

convertf -p par.PED2EIGENSTRAT

Printed to screen:

parameter file: par.PED2EIGENSTRAT

**warning: dubious parameter, please check the parameter name

I have not yet found a similar error online, and although convertf seems to finish, it does not produce a .geno file.
Any ideas on how to fix this issue would be greatly appreciated!
