Dear SPM Expert,
I am new to fMRI analysis and I am worry about outside activations. I know that outside activation can be caused by many factors and that it is common (accordingly to message in the archive).
But for my data, it seems to be very important activation outside the brain.
1. Should I worry about that?
2. How to remove it or to fade it?
In attachments:

smoothed normalized EPI image: wfunct.png
batch including the parameters of the analysis: Combine2Runs.m
I hope you'll have time to respond. A response will be really appreciate.
Regards,
Steve
