Flip L/R (left / right)
I'm starting to use MRIcronGL after using MRIcron.
Is there a way to flip L/R for an image with scripting? This option exist in MRIcron and is very important since Neurosurgery systems are working with images in which Right is Left and Left is Right
Thank you
Hadas

RE: Flip L/R (left / right)
The current version displays images in neurological convention
(left on left). I have submitted an enhancement request for
radiological convention (left anatomy on right side of
image).
https://github.com/neurolabusc/MRIcroGL/issues/12
As I understand it, the radiological convention assumes one is viewing axial slices above the head and coronal slices from behind the head. While radiological convention assumes you are looking at axial slices from the feet, and coronal slices from in front of the individual. Therefore, the images are not actually flipped, and the 3D renderings are identical for radiological and neurological convention. It is a little tricky to implement as we need to ensure that the drawings created by the user are saved/loaded correctly, that the MNI coordinates do not change (left is always negative), etc. In the meantime, if you download the MacOS version of MRIcroGL you will see that it contains the companion program MRIcro which does provide the option to view in radiological convention (Preferences, "2D Radiological View" checkbox).

The latest release (14 July 2017) includes a "Radiological" menu
item that allows you to toggle between neurological and
radiological views. For details

Is there a way to flip L/R for an image with scripting in the latest version ? This option exist in MRIcron and is very important since Neurosurgery systems are working with images in which Right is Left and Left is Right

You can change the viewing between radiological and neurological convention by opening the Preferences window and toggling the
"Radiological Convention" check box.
