WebOct 17, 2015 · The problem I have is that when I try to do calculations by group, only the allele i.d.s present in the group are recognized, so I'm struggling to find code that can tell me e.g. the proportion of G's for locus 1 in all 3 groups. Simple example, calculating a sum (not proportion) for the first allele at each locus: Webaction = 1: Assume all alleles are coded on the forward strand, i.e. do not attempt to flip alleles action = 2: Try to infer positive strand alleles, using allele frequencies for palindromes (default, conservative); action = 3: Correct strand for non-palindromic SNPs, and drop all palindromic SNPs from the analysis (more conservative).
