I've encountered a problem while trying to generate the ssm_data.txt file using a .vcf file

The command is python ~/virtualenv/phyloWGS/phylowgs-262325b219e6d31f672791a05c6f927a18963ded/parser/create_phylowgs_inputs.py --cnvs S1=438CNVs.txt --cnvs S2=449CNVs.txt --cnvs S3=453CNVs.txt --cnvs S4=489CNVs.txt --cnvs S5=500CNVs.txt --cnvs S6=417CNVs.txt --vcf-type S1=vardict --vcf-type S2=vardict --vcf-type S3=vardict --vcf-type S4=vardict --vcf-type S5=vardict --vcf-type S6=vardict S1=438.hg19_multianno.vcfsubclone.vcf S2=449.hg19_multianno.vcfsubclone.vcf S3=453.hg19_multianno.vcfsubclone.vcf S4=489.hg19_multianno.vcfsubclone.vcf S5=500.hg19_multianno.vcfsubclone.vcf S6=417.hg19_multianno.vcfsubclone.vcf

I tried and find there is only one sample '417' is not useful.And I don't know why.Can anyone help me?
