I currently a vcf file which describes in one file the variant call for all samples at all variable positions eg:
sample1, sample2, sample3, sample4, sample5 1 A A T A T 5 T T G T G
I want to convert to the vcf type which shows the call for a variable positions for one sample only eg:
sample1 1 A 5 T
I'm sure I used to know a programme which could do this - any ideas?
