Dear Freesurfer Community,
I have a question regarding the formatting of the FSGD file while doing an analysis with Xhemi. First the --y file was created as previously explained in another discussion ( https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg63965.html). That is, mris_preproc with --xhemi and no --fsgd flag.
If I understood correctly, that would create a mgh file with the following order: sub01lh, sub01rh, sub02lh, sub02rh... Then the FSGD file while running mri_glmfit would be: GroupDescriptorFile 1 Title xxx Class sub Variables var1 Input sub01lh sub var1_lh_sub01 Input sub01rh sub var1_rh_sub01 Input sub02lh sub var1_lh_sub02 Input sub02rh sub var1_rh_sub02
Would this be correct? If so, what would be the best case for specifying a variable like age? Just repeating the value 2 times?
As always, thanks in advance
Kind Regards
José
What are you trying to test? Usually you don't have lh and rh in the same glm

Thanks for your answer.
I want to correlate TMS values in 17 stroke patients. Following the instructions provided to Anders in this link https://www.mail-archive.com/search?l=freesurfer@nmr.mgh.harvard.edu&q=s... I created the --y file that joins the affected hemispheres together and the unaffected hemispheres together. I omitted the --paired-diff flag. When I run mri_glmfit with --fsgd it asks for 34 inputs. I am guessing those are for the 34 hemispheres of the patients in the order mentioned in my first email. Would this be the right way to correlate the variables?
In short, I am trying to test if there is a difference in cortical thickness, while adding covariates, between the affected and unaffected hemispheres in stroke patients.
Thanks in advance

If you are trying to determine whether the hemispheres are different, then you need to do the subtraction between the hemis (ie, the --paired-diff). If you want to look at the hemispheres separately, then don't combine them in a single file

There are not any restrictions, just do the same as you would for a non-paired analysis. In any event, you are creating a linear model y = a +b1*x1 + b2*x2 ... where y is the input (paired diff) and x1, x2, etc, are your factors. You are the one who knows your data and what models would be appropriate

I believe I found my problem. I was trying to run the analysis with xhemi. Therefore it asked for 34 inputs (17subjects * 2 hemispheres). I was doing it that way because I flipped the hemispheres of the right affected stroke subjects. That was done with fscalc mul -1.
Now I have another question, would it still be possible to flip the hemispheres with fscalc while doing a normal group analysis? Or is there another way to flip them? I want to flip the hemispheres to have all the affected just in one side (e. g. the left hemisphere).
Thanks in advance.

what do you mean "flip" them?

I believe I found my problem. I was trying to run the analysis with xhemi. Therefore it asked for 34 inputs (17subjects * 2 hemispheres). I was doing it that way because I flipped the hemispheres of the right affected stroke subjects. That was done with fscalc mul -1.
Now I have another question, would it still be possible to flip the hemispheres with fscalc while doing a normal group analysis? Or is there another way to flip them? I want to flip the hemispheres to have all the affected just in one side (e. g. the left hemisphere).
Thanks in advance.

External Email - Use Caution
I have a group of stroke patients. Most of them have a left-sided stroke, the others right-sided. I would like to swap the affected right hemisphere with the unaffected left hemisphere in the patients with a right-sided stroke. I have done that successfully following the instructions with xhemi, but is there a way to achieve that for a regular group analysis (e. g. using fsaverage as the target and not to fsaverage_sym).

You'll have to use fsaverage_sym since you are swapping sides. To do a "normal" group analysis, you'll have to first run mris_preproc on all the subjects who have the unaffected on the left, then again for those on the right. This will give you two files. run mri_concat lh.fsaverage_sym.mgz rh.fsaverage_sym.mgz --o all.mgz then use all.mgz as input to mri_glmfit
