Dear Ziad,
I have two groups of subjects. And I get the subject.1D.dat and subject.niml.dset for each subject by using 3dVol2surf. I want to get mean value at each node from these two groups. In the old version of suma.doc, it tells to do as followed:
1deval -a 'DataSurf_s1.1D.dat[6]'
-b 'DataSurf_s2.1D.dat[6]'
-c 'DataSurf_s3.1D.dat[6]'
-expr '(a + b + c) / 3'
-index 'DataSurf_s1.1D.dat[0]'
> DataSurf_mean.1D.dat
So that I get the DataSurf_mean.1D.dat as the mean value at each node for a group of subject. And it is why I want to use the ScaleToMap, I want to show the DataSurf_mean.1D.dat in SUMA. To see, if there is something different in these two group.
I want to know how to get the mean value at each node from these two group by using subject.niml.dset. In my opinion, if i get the mean value at each node by using subject.niml.dset, I can show it directly by SUMA. But I am not sure how to use this kind of file( subject.niml.dset). Could you tell me how to get the mean value at each node for a number of subjects by using the niml.dset file,( get from the -out_niml opinion by 3dVol2Surf). Thanks very much!
