Hi,
I have a quick question about how to create my stim files. Here are the details:

1. I have 3 different tasks for each subject
2. each task is for 6 sec.
3. TR is 2.2s (time between each scan)
4. Have 346 subbricks in each EPI.

starting time for the entire run for each of the task is as follows:
-------------
hold 22.5 41 59.5 78 96.5 115 133.5 152 170.5 189 207.5 226 244.5 263 281.5 300 318.5 337 355.5 374 392.5 411 429.5 448 466.5 485 503.5 522 540.5 559 577.5 596 614.5 633 651.5 670 688.5 707 725.5 744 760

, it gave me these warnings
** warnings for local stim_times format of file /home/pshuk/STIM/times_hold.1D
