bcftools filtering on INFO fields

Question

[Stephane Plaisance]

below is a piece of my VCF where I try to extract rows with SUPPORT>10 but fail to specify such filter.

I tried: bcftools filter -sFilterName -e 'INFO/SUPPORT>10' variants.vcf (typo edited) result is no filtering with all the input going through I do not find a page with working examples

bcftools 1.9

Isn't it INFO/ and not INFO\? Maybe that's why the filter doesn't work well.

[Stephane Plaisance]

You are right, only '/' is valid but does not work for me Should the VCF be bgzipped and indexed or does this normally work on plain text?

[Stephane Plaisance]

One of these bad days, I used -e (exclude) instead of -i (include) Sorry about this! It now works (of course)
