External Email - Use Caution
Hi Dougles,
Thank your for your reply. Now I am using FSFAST, but I didn't find flags in prepro-sess which can be used in combing or dividing fMRI data. Using the following code I could get three files for each run (left cortical surface, right cortical surface and sub-cortical volume):
*preproc-sess -sf subjects -fsd task_name -sliceorder so -surface fsaverage lhrh -mni305 -fwhm 5 -per-session*
Can I use preproc-sess to combine files from different runs, and discard the first 4 time points of each run? If so, could you please give me a example?
Thanks and best,
Zhi

Are you using FSFAST? If you run the preprocessing (preproc-sess), then it will get you most of the way there.

May I ask how can I modify the surface-based fMRI data, such as combing two independent sessions into one or dividing one 4D into a series of 3D surface-based fMRI files in which each one denotes a single volume/TR? Thank you very much.
Best wishes,
Zhi
