Would be very grateful for help.

I have a VCF.gz file for imputed SNP data. I know for a fact that this file contains imputation (INFO) quality scores as in a subsequent QC step I've used bcftools to only keep SNPs with an INFO score >0.70 bcftools view -Ou -i 'INFO>0.7'

However, I am struggling to understand how to view the actual INFO score for an individual SNP from the VCF.gz file.

Any ideas!?

Thanks for replying Pierre. Unfortunately I've already tried to find the solution in the manual but have had no luck. Thanks for your time.
