mris_preproc only uses the fsgdf to get a list of the subjects to include. You don't need to spec an fsgdf with mris_preproc. You can use --s or --f instead.

Hi,
I would like to analyse my data without using the mri_glmfit, because it is not flexible enough for my current purposes. But I would like to use mris_preproc and surf2surf in order to get the data into common space. However, when executing the mris_preproc I am required to specify a FSGD file, i.e. a design (variables, regressors etc.). I am wondering if that influences the processing of the data in any way - before mri_glmfit of course. So, what I am doing is just loading the ?h.FSGDF.thickness.10.mgh file that is the output of the surf2surf script, into Matlab and doing the statistics there. However, I am worried that the mris_preproc script may be using the information from the FSGD file to alter the measurements in any way. Of course, I turn of the reshape that is default in surf2surf. Are there any other options I should turn off or change?

Thank you!
