What is the best method for correcting task-fMRI head movements in a case study with SPM (1st level analysis only) ?
My main problem is the presence of significant activations (clusters) which seem to be false positives linked to movements. Due to the format of the study, it is not possible to simply exclude these subjects.
I tested different methods with SPM:
- 6 movement parameters (6mp)
- frame censoring (FD, DVARS)
- rWLS with or without pre smooth image
- rWLS + 6MP with or without pre smooth image
and FWE p
