I do want to use a program which requires a .map file like structure (Chromosome, SNP name, cM, Base pos). The problem is that I don't have the position in cM - is there any way to implement this information from existing genetic maps on the net?

If you are using plink then you can leave CM column as 0.

"Most analyses do not require a genetic map to be specified in any case; specifying a genetic (cM) map is most crucial for a set of analyses that look for shared segments between individuals. For basic association testing, the genetic distance column can be set at 0."
