Dear Douglas,

In these emails I asked to you how to flip the left-right orientation of an image in PIL orientation and you recommend to me this command

mri_convert --in_orientation PIR t1_flip.nii t1_flip_flip.nii

All have worked fine but now I am in the same situation with an image in RAS orientation. Which command should I use to flip the left/right orientation of an image in RAS orientation?. As I explained in my previous emails, the orientation is fine. The reason is that am using a software to detect brain lesions that only works in left hemisphere and my subject have the lesion in the right hemisphere. After the lesion estimation I need to flip the left-right orientation.

Thank you very much for your time and attention.

Best regards,

You can try,
mri_convert --in_orientation PIR t1_flip.nii t1_flip_flip.nii
but I'm not promising anything

Dear Douglas,

My image is in the correct orientation. The reason is that am using a software to detect brain lesions that only works in left hemisphere and my subject have the lesion in the right hemisphere. I tried it with the following command and it works

mri_convert --in_orientation PIL t1.nii t1_flip.nii

Now I would like to come back to the original orientation, which command should I use?

Thanks in advance.

Best regards,

Is the image in the wrong orientation (ie, is it not truly in PIR) or do you want to change the orientation? doing a left-right swap is more than changing the orientation

Dear Freesurfer experts,

Which command should I use to flip the left-right orientation of a T1 image?. Actually my image is in PIR orientation, I used the following command

mri_info --orientation '/home/rmn/Desktop/study/E03/3d/coanat_E03.nii'

PIR

Thanks in advance,

Best regards,
