How large is the difference between 23andme data and ftdna data used on gedmatch?

[Lek]

I just uploaded DNa land data that is converted to 23andme on to gedmatch. Even though it said it misses X-DNA or something but still worked. do you have any examples of calcs used with both data and how much difference is there ... like for example eurogenes k15

[Voskos]

if it misses the x chromosome results could differ, no?

you should have converted the concatenated file from ftdna.
