Hi Xiaojian, you can use mri_vol2surf or mri_vol2vol. doug

ps. Please send these types of questions to the freesurfer list and not to me directly. Thanks!

Hi Dr Greve,

Thank you for your prompt reply.

By "registration matrix", do you mean the matrix in "register.dat"? Could you please remind me how to apply it in all the frames? I am using spm to process all the data. Maybe there are some freesurfer functions to apply the matrix for all the frames. Or any help page in FreeSurferWiki?

Again, thank you for your time.

Hi Xiaojian, what is usually done is to run motion correction on your fMRI time series picking the middle time point as a reference. Then registration matrix for the middle time point will be appropriate for all the frames in the time series.
