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 [,1] [,2] [,3] [,4] [1,] -1 0 0 128 [2,] 0 0 1 -128 [3,] 0 -1 0 128 [4,] 0 0 0 1
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, - Dipterix
