Dear FreeSurfer Developers,
We are using your longitudinal processing pipeline (version 6.0) for our study (n=140, 3 timepoints). Our
scanner was upgraded a year ago and the a filter was used on the
raw images to adjust for hyperintensities in the images due to using a multi-channel coil.
At this point, our
bases have already been processed and consist
of three timepoints with a mix of filters: T1 no filter, T2 no filter, T3 with filter. Since we have invested many resources into
the manual editing process, we want to try to retain all the manual edits that have been done to the base. We still have the original scan and the filtered scan for
each subject. We have some ideas on how we might be able to retain the edits, but would you be able to provide input
regarding whether this seems reasonable? Your feedback is greatly
appreciated!
Plan A:
1) Create a new T3 cross-sectional with the correct nifti
2) Run recon-all on the existing base
Q: Will this retain
the previous manual edits AND incorporate the new cross-sectional image?
Plan B:
1) Create a new T3 cross-sectional with the correct nifti
2) Create a new base
Q: Is
it possible to transfer data
from old manual edits to
a new base? If so, how?
Thank you!
