Hi, I believe the example_func file is the middle time point from your 4D series, and this gets created automatically. If it's not in the output (i.e., <something>.ica/example_func.nii.gz), then perhaps you have another error somewhere earlier in the log?

It doesn't seem to be able to find "example_func". I assume that this is just a renamed version of this subject's functional data, but I don't know why the program cannot find it. Any guidance would be appreciated.
