Hello!
I keep having 2 somewhat related problems:
1. How to convert a single coordinate from MNI305 to surface. Previosly Doug suggested to try the example 8b in https://surfer.nmr.mgh.harvard.edu/fswiki/CoordinateSystems. However, that one is about moving a coordinate from 152 to 305. I would like to know how to show that MNI305 coordinate on a surface so I could eyeball it with tksurfer. Maybe one of the examples on that page is the one I am looking for but I don’t understand which one it could be.
2. How to transform a volume between MNI152 & MNI305 spaces. I tried: a) mri_vol2vol --targ ${my_volume_in_MNI305} --inv --mov $FSL_DIR/data/standard/MNI152lin_T1_2mm_brain.nii.gz --reg $FREESURFER_HOME/average/mni152.register.dat --o I_hope_this_volume_is_in_MNI152 b) mri_vol2vol --mov ${my_volume_in_MNI305} --MNI152reg --o I_really_hope_this_volume_is_in_MNI152
Neither of these methods seem to work. a-method moves the image too much anteriorly, and the b-method posteriorly. Thank you in advance, any help will be greatly appreciated!
Thank you so much! Lauri
