Hi,
I'm sorry to bother you all, but when I am performing a vertex analysis I don't get a .vtk file in the shape_analysis order. Do you have any clue what I did wrong?
What I did so far:
I would like to perform a shape analysis in the left caudate between 12 subjects which performed good or bad in a task. Therefore I set up the following design matrix:
1)select highter level/non-timeseries design
2) 12 = number of input. (4 bad ans 8 good performers)
3) EV's = 1, Contrasts = 1, FTests=1
4) titel bad_good
Matrix:
Group EV1
1 1
1 1
1 1
1 1
1 -1
1 -1
1 -1
1 -1
1 -1
1 -1
1 -1
1 -1
Afterwards I typed in the command:
first_utils --vertexAnalysis --usebvars -i L_Caud_all.bvars -d bad_good.mat -o shape_analysis/bad_good_LCaud --useReconMNI
I tried it for both, naive space and MNI. But the only files I can find in the shape_analysis folder are bad_good_LCaud.nii.gz and
bad_good_LCaud_mask.nii.gz but no .vtk file.
I'm happy for any suggestion
Many thanks!!
Stefanie
