merging vcf by vcftools

Dear All I have tried to merge two vcf files by using vcf-sort, gzip, tablix followed by vcf-merge. The resultant merged file contains variants on chromosome 1 only. Any comment/help would be appreciated.

With all respect, how can we help with these informations ?

We need to have a look at the command lines you used, the VCFs you are working on (or at least a representative parts of these VCFs) and the result you get.

In addition to the above, you should use BCFtools (merge or concat, depending on what exactly you're doing) and not VCFtools. There's even a written line somewhere by one of the authors of VCFtools where he encourages people to switch to BCFtools.

i have the same problem,is there any answer later?

I'm using picard MergeVcfs option and never had an issue with that... Maybe you should try it!
