Answer 1

Please read the manual. You have to use the --keep-info flag. It's literally called "keep INFO" :)

Read "INFO FIELD FILTERING" under https://vcftools.github.io/man_latest.html#SITE%20FILTERING%20OPTIONS

[claudia_io_p]

but not recalculate the INFO, only keep this

[Ram]

Might have helped if you'd mentioned that in the original post :) I'm not sure how INFO can be recalculated on the fly by such a simple tool - maybe a GATK Walker (such as SelectVariants) might help.
