Comment: C: Top/Bottom Confusion For Illumina Snp Calls
... Thanks. It seems to me that this naming convention conflicts with what is presented in ILLUMINA.ILLUMINA_Human_1M.xml. In the naming convention file, rs536477 is A/G and TOP. However, the rs536477 entries in the XML file are A/G and strand='bottom'. Does strand have a different meaning in the XML fi ...

One of the problems that I am facing is that I don't have the original data. All I have is the Illumina SNP processed file with the SNP number and genotype call (AA, AB, ...
