Dear fs-fast wizards,
doing monkey fMRI in Bremen (block desing so far) I run into the problem that analysing the data from one session does not lead to well defined activation maps. Therefore I would like to pool over several sessions (always within one subject). Unfortunately I have did not manage to always position the slices at the same position, I recorded a different number of runs each session. Now my assumption is all I need to do is define according df and sf files and be done with. But at what stage (mc-sess, spatialsmooth-sess, mkanalysis-sess.new, selxavg-sess, mkcontrast-sess or stxgrinfer-sess)? Is it advisable to motion correct all session runs together, or combine the data after that step? So excuse me for my uneducated question, but I would be delighted to tap into this list's vast knowledge before debarking into computationally long experiments. One more question, is it necessary/helpful to record low-res anatomicals before functional runs to register separate sessions, or is this step avoidable.
Regards Sebastian
