i have a group of 49 subjects run through first, i have run concat_bvars
for the regions that i am interested in. i used Glm to set up the design
matrix as described (groups are broken into 2 EV with a 1 or 0, the group
column is all 1s). I have set up group contrasts as 1 -1.
however when i try to run the vertex analysis:
first_utils --usebvars --vertexAnalysis -i all_R_Amyg.bvars -d design.mat -
o group_R_amyg --useReconMNI
i get this error:
terminate called after throwing an instance of 'NEWMAT::SingularException'
Any ideas?
All of my subjects have the corresponding files, and everyone is accounted
for in the design.mat (49 subjects in bvars and .mat)
thanks,
-chris
