Dear FS experts
If I use the --paired-diff option in mris_preproc, I know that the different time points of a subject has to be adjacent inputs in the FSGD file.
Do I also have to specify the different time points as different classes or as only one class in the FSGD file?
Thanks in advance Regards Jürgen

Hi If you have pairs of one group then you need to specify one class.lets say subj1 and subj2 belong to one pair and subj3 and subj4 are also one pair. class maininput subj1 maininput subj2 maininput subj3 maininput subj4 main If you have two groups then you would need to specify two groups.class mainclass anotherinput subj1 maininput subj2 maininput subj3 anotherinput subj4 another I am not sure what you mean by two time points. If its a longitudinal study then I think you need to go through recon-all-long and I am not sure about the statistics thereafter. Best,Raka
