Sorry if this has been posted before and/or if it's a ridiculous question.

I have access to only the BRIMM-p genotype calls for a set of human samples from a collaborator and this file is the format: probe_id A-100 A-1 A-2 A-4 A-3 A-5 A-6 A-11 A-12 A-13 A-14 A-15 A-16 A-17
SNP_A-1780520 1 -1 2 2 2 2 2 2 2 0 2 2 2 2 2 2 2

etc

How can I transform this into actual dna calls (AA AT AC etc)? And the SNP id into coordinates? Surely there must be a script somewhere that I can't find!

thank you in advance!
