Hi SPMers,
We have a first-level analysis for which several of our contrasts
have been showing "streaks" of activation (see attached image). We are
wondering if this pattern of activation could possibly result from
normal/benign variance, or whether it implies something seriously
wrong with either our data or preprocessing.
The motion for this subject was generally good (all runs < 1.2mm for
all 6 parameters). Preprocessing steps included ArtRepair bad slice
detection and bad volume detection.
Many Thanks,
