Vcfsimplify error

[tamaram444]

I'm trying to run vcfsimplify.py to filter snps from a VCF file, but it keeps returning an error (see below). Any help with this would be much appreciated.

andrea@T3610-U:~/introgressionbrowser$ vcfmerger/vcfsimplify.py -i /home/andrea/introgressionbrowser/data/PvTFL1y_refV2_Chr01.recode.vcf -o simp_snp
