You can just use mri_concat file1.mgh file2.mgh ... fileN.mgh --o stack.mgh

External Email - Use Caution

Hello,

I have a surface measure calculated for each of my subjects, which I have already resampled and smoothed on fsaverage using mri_surf2surf, i.e for each subject I run: mri_surf2surf --hemi <hemisphere> --s fsaverage --sval <surfMeasureSubjX> --fwhm <FWHM> --cortex --tval <output> I now want to stack the outputs of the commands above, so that I can give the stacked image as an input to PALM. I think I should use mris_preproc for that, but I'm not sure if the subjects (the argument after the --s flags) should be the original subjects or fsaverage - given that my surface measures are already resampled to fsaverage.

That is, I'm not sure if the correct command is (for 2 subjects)

mris_preproc --out <outfile> --target fsaverage --hemi <hemisphere> *--s subj1 --s subj2* --is <surfaceMeasureFileSubj1> --is

<surfaceMeasureFileSubj2>

*or *

mris_preproc --out <outfile> --target fsaverage --hemi <hemisphere> *--s fsaverage --s fsaverage* --is <surfaceMeasureFileSubj1> --is

<surfaceMeasureFileSubj2>

Thanks!
