Dataset (PLINK format): conversion from b36 to b37

[ElMichael]

Hi,

I have a dataset in the binary PLINK format from the Illumina 1M array. Samples were genotyped on the array, designed to human genome build 36. But now I need to convert it to b37. What is the best way to do it? I read about some Illumina conversion files but didn't find them.

Thanks!

liftOver the map file.

But what is about those snps whose position was changed even to another chromosome? And snps whose rs ID was changed?

I think the liftover would fix the chromosome issue (probably, others? comments?) but not sure about the rs ID mapping.

Thank you, turnersd!
