Hi,
I'm attempting to do some longitudinal processing on a set of data with subjects with up to 4 timepoint scans: Baseline, Midpoint, Final, 12 months after Final.
When visually checking over a subject in Freeview, I notice that all of my Midpoint runs are left-right flipped, where the other 3 timepoints' scans are congruent with one another.
What can I do to flip these Midpoint volumes left-right before I rerun them all in recon-all "-all"?
As well, since these are going to the same subjects for my longitudinal design in creating a 'base' file we have to ensure that we maintain the same orientation of the brain across all timepoints (left-right)?
Thanks in advance,
- Bryan
How did you convert to mgz? Did you start with dicoms and use mri_convert? How do you know they are flipped?
