Dear friends of SPM,
I am wondering whether or not to include the head motions (rp_*.txt) into the 1st level analysis. Somebody please educate me what's the con and pros of including head motions as regressors? If it could not increase the statistical power significantly, I may not bother doing that.
Thanks a lot!
Xin
