Dear SPM-experts,
I have nearly the same error as described above.
When I'm trying to do my second level analysis (flexible factorial) I also get the message "Please check you data. There are no significant voxels".
But this error message occurs only if I include two specific subjects (overall, I include 14 subjects but subject number 11 and number 12 are the "strange" ones). In other words: Doing the second level analysis with one of the two subjects (doesn't matter if number 11 or number 12), it works fine but if I'm including both subjects it doesn't work.
I already tried the following things:
- full factorial (failed)
- including not every contrast of the two specific subjects (failed)
- looking at the data via "checkreg" (looked fine)
- checking the baseline contrasts of both subjects at first level (looked different and there were significant voxels)
- t-test that worked fine with both specific subjects.
I would be very happy if anyone could explain this error and a possible solution.
Thank you for your help in advance,
Katharina
