Thanks, Matt!
I just uploaded the tar'd directory on the link you sent me. A couple of notes to make your life easier:
1) The warning message can be seen on ./copeX.feat/report_log.html, and it happens for all the contrasts.
2) I had wondered if the warning was being caused due to having more EVs than lower level FEAT directories. It turns out that the warning is still there even if I run the lower and higher level models with a single EV and COPE. Indeed, if we look at the warning message carefully, it actually says that the number of evs is 1 while the number of points is 4. An example of the warning is pasted below:
WARNING: The passed in varcope file, var_filtered_func_data, contains voxels inside the mask with zero (or negative) values. These voxels will be excluded from the analysis.
nevs=1
ntpts=4
ngs=1
nvoxels=922351
Running:
nmaskvoxels=922351
Thank you very much for your willingness to help again. Hopefully we'll be able to figure this out.
Best,
