Thanks Bruce,

should the hemisphere's be processed separately, or how do I signify lh and rh simultaneously?

Also, should the fact that after running mris_make_surfaces, it says "detecting dura using 0 echos from memprage_echo%d.mgz" be worrisome? I've got 4 different echos, all mgzs in the directory. I have a feeling I'm doing this incorrectly.

Hi all, combed through the mail archives to figure out how to work with multi echo mprage, found what I need but I wanted to confirm which of these two commands is the appropriate mris_make_surfaces -dura memprage_echo%d.mgz 4 subjid lh/rh mris_make_surfaces -dura memprage_echo%d.mgz do the subjid and hemispheres need to be specified as per the 1st line? jon

I input:

mris_make_surfaces -dura memprage_echo%d.mgz subjid lh

it returns:

detecting dura using 0 echos from memprage_echo%d.mgz

Should I execute the command in the same directory as the mgz's? Should they be set up or placed in a specific directory? I also, as with recon-all, exported the proper subject directory beforehand.

can you send me the full command line? It should say 4 echoes, not 0 On Thu, 9 May 2013, Jonathan Holt wrote:
