Hi There, I am running a stepwise QTL for a backcross and got the following warning message: Warning message: In lastout[[i]] - (max(lastout[[i]]) - dropresult[rn == qn[i], 3]) : longer object length is not a multiple of shorter object length I can not discern what this means. When I created my plot, the QTL curve on chromosome 3 is very odd (tried attaching it), so I suspect that the warning is connected to that odd curve plot. I tried running the fitqtl just to see what would happen and got an error (Error in solve.default(t(Z) %*% Z, t(Z) %*% X) : system is computationally singular: reciprocal condition number = 1.49755e-24). Any thoughts about what is going on?

So dimensions of the arguments may not match?

No, without knoing what the arguments and the actual code was. Best, Uwe Ligges
