Hi all,

Unfortunately my worst nightmare was realized, and even though it looks like the group x condition interaction was significant (see post above), the post hoc GLTs are all non-significant (at FDR-corrected 0.05). How is that possible? Am I coding the GLTs incorrectly, missing post-hoc tests, reading the interaction incorrectly (I'm setting the interaction sub-brick for both the overlay and threshold), thresholding incorrectly, etc.? I've included the code below (see previous posts in this thread for the data table), and would be willing to send the MVM output file if necessary.

Thanks,
Laura
