Freesurfer experts,
I'm trying to put some subject surfaces into a template space. I have performed the following flirt registration per subject:
flirt -in $SUBJECTS_DIR/$CURSUBJECT/mri/T2.nii.gz -ref template0.nii.gz -omat $SUBJECTS_DIR/$CURSUBJECT/mri/transforms/talairach.fslmat -out $SUBJECTS_DIR/$CURSUBJECT/mri/transforms/talairach.nii.gz -dof 12 -searchrx -$D $D -searchry -$D $D -searchrz -$D $D
Then apply the flirt transform
mris_transform --trx-src $SUBJECTS_DIR/$CURSUBJECT/mri/T2.nii.gz --trx-dst template0.nii.gz $SUBJECTS_DIR/$CURSUBJECT/surf/${CURHEMI}.${CURSURFTYPE} $SUBJECTS_DIR/$CURSUBJECT/mri/transforms/talairach.fslmat $SUBJECTS_DIR/$CURSUBJECT/surf/${CURHEMI}.${CURSURFTYPE}.flirt
When I overlay the output surface $SUBJECTS_DIR/$CURSUBJECT/surf/${CURHEMI}.${CURSURFTYPE}.flirt over the template template0.nii.gz the surface is in the wrong orientation and in the wrong position, i.e. not correct.
I have tried using lta_convert to make a lta transform and I get the same result.
Any thoughts?
Thanks,
Chris.
