Hello FS experts, I have 3 groups, e.g : normal, MCI, and AD. Am I correct in my understanding that QDEC would not be applicable here?
In my subjectdir, I created a folder for mri_glmfit analyes called FSGD. In that folder, I have the FSDG file and the relevant contrasts. GroupDescriptorFile 1 Class HC Class MCI Class AD input sub1-base MCI input sub2-base AD input sub3-base HC My contrast is a simple [1 0 -1] for HC > AD. I called it HC-AD.mtx and saved it in the FSGD folder. Then, in the SUBJECTdir/FSGD folder, I run the mri_glmfit command as follows: mri_glmfit --glmdir fsgd/ --y y.mgh --fsgd g3v0.fsgd --C normal-ad.mtx My question is, what is y.mgh as shown in the examples on the Wiki? It is supposed to be an input file, but what file is this? Thank you very much!
