APTurner, can you explain? These statements look contradictory to me:

"Raw data files from 23andMe and FTDNA give the SNP location in Mb units, so that shouldn't be a problem. The companies and utilities like GEDMatch have routines to report the distance between two points in cM."

and

"AncestryDNA has said they will release the segment information sometime this year. When they do, the information will still not be directly convertible to compare to other companies. You will need to convert the Mbp to cM to be meaningful."

Thanks!
