Dear group, I ran recon-all on a T1 nii file, which is in LAS orientation. The brain.mgz turn out to be in LIA orientation. I've tried to convert the nii file to RAS (mri_convert --in_orientation LAS --out_orientation RAS ...), and rerun recon-all, but it didn't change the results. How do I make sure my output files will be in RAS orientation?
Thanks, Noam
Hi Noam
if you want your outputs in a specific coordinate system, why not just run recon-all, then mri_conver to whatever orientation you want? Internally we have a consistent orientation that you can't easily change

Hey Bruce. Originally this is what I did. I used mri_convert on the relevant nii files, but I was wondering what to do with the surfaces files. I thought it'll be easier to create all of these files directly in RAS orientation.
Thanks, Noam

You can use this version of mris_apply_reg https://gate.nmr.mgh.harvard.edu/safelinks/greve/mris_apply_reg Something like mris_apply_reg --src-xyz lh.white --lta rawavg.lta lh.white.rawavg Where rawavg.lta is created with tkregister2_cmdl --mov orig.mgz --targ rawavg.mgz --regheader --reg deleteme.dat --ltaout rawavg.lta
