Ziad/others,

Not sure if I should've started a new topic for this, since it's directly related to the SurfSmooth problem I was having.

Anyway, I am now able to smooth those surfaces I was having issues with. After smoothing, I'm running 3dDeconvolve on the surface data and trying to view the resulting output in SUMA. I have no problem doing this with the other hemisphere. In this case, the RH doesn't have any issues, but the LH does. Specifically, after running the commands below, I tried to "Load Dset" via the Surface Controller. I get several text popups with the following error messages:

"Cannot assign dset to SO or its local domain parent"
and
"Node index range outside 0 and SO->N_Node"

Importantly, I also got the same errors when trying to load the output of 3dDeconvolve on a non-smoothed dataset (so, smoothing doesn't seem to be the problem). Here's the 3dDeconvolve command I ran:

I've uploaded the relevant files for you to try to view. The following (among others) are in an archive called 'AdamZiad080126.tgz':

CW_AttnSW_LHsrf.niml.dset -> LH smoothed 3dDeconvolve output
CW_AttnSW_nsmLHsrf.niml.dset -> LH non-smoothed 3dDeconvolve output
script -> the commands I ran on the LH data

Thanks again for all your help,
Adam
