Dear AFNI experts,

I'm totally new in afni. Here are some questions about how to write truly stimulus timing file and I really hope you can help me. Thanks a lot!

My experiments is slow event-related design. There are 8 runs and 11 types of stimulus conditions in a scanning session, each run consisted of 24 trials (1 trial=14s). However, the number of stimulus condition is different in each run, even there are not the condition in some runs.

For example, in the FT3.txt, there are not the third condition in the second run and the fifth run. And The warning message I keep getting is: ** warning for local stim_times format of file FT03.txt, - 6 rows does not match 8 runs. Therefore, what is the right way to write these stimulus timing files ?

Thanks a lot in advance.


% cat FT03.txt
