Dear Yangmei,
If you are averaging runs with a mid-level analysis, where some runs measure A and some B. Then if the lower-level contrasts are of the form
A <blah> <blah> <blah>
B <blah> <blah> <blah>
Then a mid-level design averaging cope1, will result in the cope1.feat output folder containing the copes to import into the next level.
If your lower-level contrasts were of some different structure - e.g.
A <blah> <blah> <blah>
<blah> B <blah> <blah>
Then you’re mid-level design would need to work on both cope1 and cope2 inputs, with the copes to import into the next level being split between cope1.feat and cope2.feat.
Hope this helps,
Kind Regards
Matthew

Dear Matthew,
Thanks for your time and patience! You kind help is greatly appreciated!
I am sorry to bother you again.In fact, I did not understant the sentence that "so if you are running the design below on ( e.g ) cope1 of each run, then cope1 needs to hold the quantity you wish to average for each run" in the last email. Could you give me
more details or an example?
All the best,
Yangmei
