RE: Unrecognized field name "F".
Hi Felipe,

Not sure but as far as I can tell this error indicates that there are no voxels with valid data for all subjects, so there may be some problem with your first-level analysis results (e.g. they might contain all zero values at least for one subject?). Could you check if in the first-level analysis tab you are seeing some particular subject(s) with no connectivity data?

Best
Alfonso
