Dear FSL listers,
I'm having a similar problem to Akira in this post. Did you find a solution by the way?
Randomise seems to throw an exception when the number of columns in the matrix is greater than the number of rows.
Under normal circumstances there would be more subjects (i.e. rows) than EVs (i.e. columns), but as I understand it the whole point of the setup_masks script is to add an EV of a single 1 and multiple 0s for each subject/row. This gives a square like this:
/Matrix
1 0 0 0
0 1 0 0
0 0 1 0
0 0 0 1
However, with the addition my two group EVs and 2 covariate EVs, the resulting final matrix in the .mat file is always going to have more columns than rows, e.g.:
/Martix
1 0 1.3 12 1 0 0 0
1 0 1.2 19 0 1 0 0
0 1 1.6 14 0 0 1 0
0 1 1.1 13 0 0 0 1
Any thoughts much appreciated,
James
