Fatal error with sm-list

The program is being run with a sm-list whose samples are all in the evac table (4789 samples). The VCF has slightly more samples 4815 and generates a FATAL error. I was expecting the subset to occur first and then a check for that the VCF samples have PCs. This is easy enough to get around by subsetting with bcftools view -S gcad_samples_4789.txt but it would be nice to be able to select the subset with ruth.

ruth --vcf adsp5k.manta.indels.norm.vcf.gz --evec adsp5k.evec  --field  PL --out adsp5k.manta.indels.norm.ruth.4789.vcf.gz --sm-list gcad_samples_4789.txt
