Flipped VOI in MRIrcoGL
We are segmenting CT scans in MRIcroGL and after saving the VOI the resulting overlay flips the VOI to the opposite side.  Any fixes for a Macbook Pro?

RE: Flipped VOI in MRIrcoGL
Dear Benjamin,


could you solve your issue with this?
I'm having a similar problem: After saving my drawn lesion masks to .voi and .nii Files, one of them is flipped left-right. Sometimes the voi-file is the 'correct' one, sometime it is the nii-file.
I would be very thankful if someone knew a solution. With this problem I can never trust my lesion file to stay in the correct orientation when saving it.

Thanks,
Anna

Anna,
  I suspect your issue is fixed with the upcoming release. Can you tell me the operating system you are using (Windows, Linux, macOS) so you can test out the upcoming release to ensure the issue is resolved.

Chris,

We are using MRIcroGL to segment MRI, and until now, we keep facing the same issue. We are using macOS for the delineations.
