problem with var and var.ex

[Lili]

Hi,
I have a pseq project by reading in several single VCF files. I want to include/exclude some regions for analysis and I uploaded a var file looks like this:
REG    test    chr22:16220000..16242500
REG    test    chr22:17150000..17394100
...

When I run command below I can get SNPs in target region for sample1, but not the rest of samples.
pseq proj1 write-vcf --mask var=test

#CHROM	POS	FORMAT	sample1	sample2	sample3	sample4
chr22	16222618	GT:GQ	1/0:90	.:.	.:.	.:.
chr22	16224667	GT:GQ	0/1:83	.:.	.:.	.:.
chr22	16224740	GT:GQ	0/1:95	.:.	.:.	.:.

 

When I run command below, I can exclude SNPs in target region in sample1, not the rest of them.
pseq proj1 v-view --mask var.ex=test

#CHROM	POS	FORMAT	sample1	sample2	sample3	sample4
chr22	16222618	GT:GQ	.:.	1/0:90	1/0:90	1/0:90
chr22	16224667	GT:GQ	.:.	0/1:83	0/1:83	0/1:83
chr22	16224740	GT:GQ	.:.	0/1:95	0/1:95	0/1:95

It looks like the var and var.ex only works on the first sample. Is there anything wrong with my code?
Please advice. Thanks.
