Edit mode works only in one plane

[valosekj]

In FSLeyes edit mode, I can edit binary mask (segmentation) only in one plane. In other plane, there is no action when I click by mouse. See video below:

I tried both "pencil" and "erase" tools. I also tried FSLeyes from two FSL versions (6.0.4, 6.0.5). The bug persists also when I create new empty mask.

I get following errors in terminal:

@valosekj Apologies for the delay. Can you check what version of FSLeyes you have installed? You can find out via the FSLeyes -> About menu option

[valosekj]

I can reproduce the bug in several FSLeyes versions on both MacOS and Debian.

MacOS 11.6.2

FSLeyes version: 1.0.13

paul.mccarthy@ndcn.ox.ac.uk
FSL version: 6.0.5
FSL directory: /usr/local/fsl
OpenGL version: 2.1
OpenGL compatibility: 2.1
OpenGL renderer: Apple M1

Debian 10.12

FSLeyes version: 0.34.2
FMRIB Centre, Oxford, UK
Paul McCarthy
paul.mccarthy@ndcn.ox.ac.uk

Are you able to try a more recent FSLeyes version? There is a good chance that this is a bug which has already been fixed.

[pauldmccarthy]

You can create a separate conda environment with a more recent FSLeyes version with something like this:

$FSLDIR/fslpython/bin/conda create -c conda-forge -p ~/new_fsleyes.env fsleyes

And then run ~/new_fsleyes.env/bin/fsleyes

I have installed FLSeyes 1.3.3 via conda and edit mode now works!

Thank you very much for your help!
