Hi Alfonso,

I downloaded conn12.p and run the whiole process from matlab7. The setup is ok, but then in the preprocessing a different error appears immediately. Different from the one that I had before >(the out of memory). The error now is this:

??? Error using ==> fwrite
Invalid byte count to skip.

??? Error while evaluating figure WindowButtonUpFcn.

Really, I'm quite lost! I have also noticed I have problems entering the data because white I write appears in white and cannot be seen. I have to select it in order to check if it is OK. I am not sure whether it is an installation problem. I particularly have problems entering the band-pass filtering.
Thank you,
Cristina
