Hello Saeed, I'm using ,amy years for linkage analysing already many years Simwalk2 software. Simwalk2 is excellent tool for extended pedigrees with numerous inbred loops as I have from Dagestan genetic isolates (Caucasus, Russia). There is a SNP linkage option but I did not yet uset, working with genome scanned STRs. Any questions about -are welcome. Best wishes!
Simwalk2 works very well for STRs, but in a fairly extensive set of tests we did in 2006 (Am J Hum Genet 79:846-858, 2006), it did not perform at all well with dense SNPs.
