Dear All,

As you know when annotationg a vcf file each line might have more than one annotation but I would like to get only one annotation for a line? the first one only if possible.

So thanks in advance.

a variant can overlap multiple transcripts with different consequences; So why would you want to do this ?

Yeah you are right but for some reason I only would like to get only the first annotation. :)
