I run SPM5 on a Mac OS 10.5.5 using Matlab 7.6.
I have recently installed the MarsBar 0.41 in order to define and write a ROI.
I loaded the MarsBar successfully from the toolbox menu of SPM5 and tried ROI
Definition>Get SPM cluster(s).
Then, I can select the matrix, choose the contrast, define the threshold and observe the
results in the SPM graphics Window BUT the "Write ROI" menu does not show up in the SPM
input Window (bottom left window), as indicated in the MarsBar tutorial.
I do not receive any error message.
(I have the same problem with SPM2 on my Mac)
