At present, I also want use onemap for F1 genetic map construction, and download the software, it showns nedd the tkrplot to work, but I can not use the tkrplot work

I had the same problem, you need the dev version of tcl/tk, this fixed it for ubuntu:
sudo apt-get install tcl8.5-dev tk8.5-dev
(If you are on windows then I don't know)

I have ~9000 SNP markers generated from ddRAD seq. OneMap works fine until I was mapping 4 linkage groups with ~100 markers each. It gave an error,

Cross type: f2
Choosing initial subset using 'two-point' approach
Error in if (r.temp <= max.rf) r[j, i] <- r[i, j] <- get(input.seq$twopt)$analysis[k[2], :
missing value where TRUE/FALSE needed

Out of 30+ linkage groups that I mapped, only these 4 linkage groups generated an error when I tried to map them. I wonder if I have missed something?

Thanks for the help!
