[Vcftools-help] Error usinf vcf-merge

[Gil S. <gil...@gm...>]

Hi All

I used the following command -
vcf-merge S11_L001.freebayes.filtered.vcf.gz
S11_L001.samtools.filtered.vcf.gz | bgzip -c > S11_L001.vcf.gz

I received the following error while using the

Using column name 'unknown' for S11_L001.freebayes.filtered.vcf.gz:unknown
Using column name 'S11_L001.bam' for
S11_L001.samtools.filtered.vcf.gz:S11_L001.bam

This error message repeated itself many times
Why is this happening and how should I treat this?

Many thanks
