[BUG] co-registration doesn't work properly in newer versions about gannet HOT 3 OPEN

Are you able to share your data so I can explore the problem in the newer version? My email is [email protected]

Hi @peter-mri,

Firstly, .rda is not recommended. It's much better to export your data in TWIX (.dat) format.

Secondly, if you are co-registering MRS voxels that are not from edited acquisitions, you should use CoRegStandAlone.m. See these instructions for details.

Note that for muscle data, the segmentation will not be appropriate as the SPM template is for the adult brain. Happy to help you adjust this if you want to segment your images/MRS voxels for muscle (if there's an appropriate template available).

Appreciate the super-quick response Mark. CoRegStandAlone returns the same (erroneous) output. I understand that .dat files are preferred, but there are sometimes limitations saving those (they were not saved for this study). Since the software offers support for DICOM and .rda files, we were hoping to use those. I found it curious that .rda files worked better in previous versions, but not in current one. We have an acceptable work-around for our data (using 3.0), I just figured you might be interested in the changed behaviour.
