Hi,
I stumbled upon two entries in the VCF of NA12878 with the same position. I thought this is not allowed. I checked the vcf specifications at http://www.1000genomes.org/wiki/Anal...mat-version-41 and it actually says:
"It is permitted to have multiple records with the same POS".
Does anyone know what the advantage is of allowing mutliple records with the same POS? One could easily merge multiple records with the same POS into a single one. Mutliple alleles would then be listed in the ALT column and different genotypes in multiple vcf files would then point to these different alleles (0/1, 0/2, ...). Actually that is what vcf-merge is already doing now.
Am I missing anything?
Thanks a lot!
