Feng-Xian,
In the case of qdec results, those files are associated with the 'fsaverage' surface, specifically, they overlay on that surface. So one option to 'open' the files is to first load an fsaverage surface in tksurfer, and then use the Load->Overlay option to load sig.mgh onto that surface for display. You can also use the load_mgh.m matlab file to load the data into matlab, and the data is one datapoint per vertex (of fsaverage). Or dump the file ascii like this:
mris_convert -c ./sig.mgh \ $SUBJECTS_DIR/fsaverage/surf/lh.inflated \ sig.asc
where sig.asc will be one line per vertex: vno, x,y,z, sig

Hi, Thank you for your help before. And, I have a problem today. How do I open the file called *.mgh as F.mgh and sig.mgh in the dictionary “qedc”?
This problem has been nagging me for some time.
Thank you in advance!
