Hi rick,
I'm totally new in afni. I have a similar error about the "permission denied".
When running the preprocessing script, everything runs smoothly until:

./@ss_review_basic
./@ss_review_basic: Permission denied

Then running tcsh @ss_review_basic
gives:

My experiment is slow event-related design. There are 8 runs and 12 types of stimulus conditions in a scanning session, each run consisted of 24 trials (1 trial=14s) and 1TR=2s. As shown above, some num TRs per stim: 6 or 13, was the timing files wrong? I have checked the time files. What other causes may there be?

Thanks a lot in advance.
