Dear BioC users,
I'm using LimmaGUI in R2.7 to analyse my microarray (miRNA exiqon
v.10.0) experiments...
But I'm not be able to solve this type of error that appearing
constantly when I try to compute the linear model fit, particularly
this error ever appears when I include in the model only the genes and
excluding the controls. I made for this a specific SpotType file:
SpotType ID Name Color
gene * *mmu black
control NO_NAME NO_NAME yellow
How can I resolve the error message: "asMatrixWeights(weights,
dim(M)): weights is of unexpected shape", using LimmaGUI packege in R?
Besides, there is no problem if I compute the model on all spots.
Can I modify in any way the spot file?
Is there a possibility to solve it in LimmaGUI or a possibility to
modify the matrix array when excluding some spots?
I hope someone can help me!
Thanks a lot and best wishes,
Andrea
