Unfortunately I get such error message with the matrix 0 0 0 1
ERROR: dimension mismatch between X and contrast contrast.mtx X has 3 cols, C has 4 cols
Instead if I use 0 0 1, it works
Best,
RAFAEL
That should have failed because it only has 3 values (should have 4). I think it should be 0 0 0 1 On 4/11/19 3:20 AM, TMS lab wrote: > > External Email - Use Caution > > You are right.
