Dear FreeSurer Wizards,

I'm trying to run the recon-all command on one of my template brains such that the resulting Norig and Torig are identical. I understand that fs always conforms the MRI to 256^3 before segmentation. I wonder if there is any way that I can resample the original MRI to achieve the same Norig and Torig?

More specifically, currently the Torig (vox to tkrRAS) is

If I resample the input image such that Norig (vox to scanRAS) equals this matrix, can I expect that "conform" does not change the orientation?

Alternatively, is there any method I can use to "predict" or reproduce the Torig from the original MRI outside of FreeSurfer?

Thanks,
