Dear all,

I think the following error has been reported already, but I could not find out how to solve it.,I basically used stand alone REX to extract WM and CSF singals from binary masks with the same size as the BOLD data. I downloaded REX from http://www.alfnie.com/software. I've used files from different subjects with different coregistered and resliced masks, I've made sure no other REX versions are in the path, but the error persists. What am I missing?

Thank,
Eugenio
