How get Genetic Positions of SNPs?

I have some datasets related to different diseases like AML, etc. The data which I have include markers’ genotypes (AA, AB, BB) and some other information like chromosome number, physical position, strand,etc. For some reasons I need to have the genetic positions of these snps as well. As I have searched so far, I could not find any exact solution for this (some suggested using ‘MareyMap’, but it also needs both physical position and genetic positions as input). Do you have any recommendation?
