Dear Free Surfers, I am analyzing fMRI time series that were reconstructed offline (GRAPPA data that needed some artifact corrections, long story). Unfortunately, the offline reconstructed f.nii do not include proper header info. I think I was able to set the orientations correctly using mri_convert, but now FSFAST preprocessing (specifically, mc-sess) fails because the headers say that the number of TRs (number of full volume acquisitions) in the measurement is 1, whereas in fact the correct value is 316.
I could not find a tool that could change the "nframes" value (mri_convert can adjust many other things but not this one it seems). Any suggestions?
