Dear Martin， Thank you for your reply. I used a paired analysis to do "two groups two times data of the longitudinal analysis".
But unfortunately, I did not make the results, and I use “mri_glmfit-sim” to find 0 vertices in mask.
My files are as follows.
Fsgd 1: (pairs.fsgd)
GroupDescriptorFile 1
Class Sub
Class Con
Input sub01_MR1 Sub
Input sub01_MR2 Sub
Input con01_MR1 Con
Input con01_MR2 Con
...
Fsgd 2: (paired-diff.fsgd)
GroupDescriptorFile 1
Class Sub
Class Con
Input sub01pair Sub
Input con01pair Con

mean.mtx: 1 -1
Are they correct in my Paired analysis? And I am trying LME now.
However, I see other people in the mailing list of the questions and replys, I realize that I may be wrong.
My two groups of two time are the experimental group (bs) and the placebo group (placebo).
I want to do “the crossover analysis” Just like:(postbs-prebs) - (postplacebo-preplacebo) Should not I use longitudinal analysis for these two groups? What kind of analysis do I need to do? Please tell me where I should look in the wiki.
Looking forward to reply, and thanks very much.
Kind regards,
Livia
