Dear SPMers,
I am working on a Fixed Effects group analysis of 7 subjects in a UNIX/
Solaris OE. I was reviewing a contrast with a simple mask and found several
interesting activations. Then I tried another mask on the same contrast and
all the activations were gone. This was already surprising, since the second
mask should have let some blobs to go through. The major problem is that
when I went back to my contrast with the original mask, the original
activations I found earlier were also gone! I found the same (almost) empty
brain as in the contrast with the second mask. I would be very grateful if
anybody could provide me with a possible cause and solution of this problem.
Yours,
Lennart
