Thank you. I did use an absolute threshold of 0.1 originally. I tried explicitly
masking with the brainmask image, and I also tried an absolute threshold of
0.2. Both changes resulted in the same error for FWE-corr. I looked more
carefully at the results when I enter p<.001 uncorr, and noticed that I'm
getting warnings in the Matlab window:
Warning: Returning NaN for out of range arguments
Additionally, my set level and cluster level p values are NaN, and the T-value
for a few GIANT clusters are in the 5*10^15 range!
This is a subset of my subjects, and when I perform the same paired t with
n=14, I do not have any of these problems.
What's going wrong?
Thanks
