dear Stephen,
thank you for your suggestion. but i had tried it, it seemed no use. the
cope files in the sigle-block group were still in size of 3*3*5, but the
cope files after combining 2 sessions with FE in the 2-block group were in
size of 2*2*2. when i feeded them all to third level analysis, the featwatch
tole me: ERROR: couldn't open head file of /stat/pe1, et. al.
maybe my problem is too special, whatever, thank you again!
best wish!
Wang, Bo

| Hi,
|
| I've not tested this, but the following should work. First
| you run featregapply on all first-level .feat directories.
| Then run higher-level analyses to combine across the 2
| sessions for group 2 - you may need to use the FE option,
| though the ME OLS option may work. Then I would have thought
| that the combination across subjects should work ok?
|
| Cheers.
