FSLeyes on windows

[sh-shahrokhi]

Hello
I managed to run fsleyes on windows natively, with some errors

First, the simple reproduction:
In an Anaconda/miniconda/miniforge prompt:

1. create fsleyes env: conda create -n fsleyes
2. conda activate fsleyes
3. install fsleyes: conda install fsleyes -c conda-forge
4. run fsleyes from cmd: fsleyes
   (it will complain about $FSL_DIR, click skip)

The resulting env:

FSleyes window:

Problems:

1. almost all sliders (zoom, brightess, contrast, ...) do not work
2. moving through slices is unstable
3. sometimes hangs on exit

some console errors:

I understand that this app is not supported on windows, but will appreciate any fix for this. I will happily help if any test/input is needed

Thanks

Hi @sh-shahrokhi, sorry, I don't have access to a Windows machine, so am unable to diagnose/fix any Windows-related issues.

Hi @sh-shahrokhi @pauldmccarthy

I agree with you, sliding is quite slow, but my main problem is when viewing in "label image" mode nothing is observed:

I would be happy to find a solution to this problem.

best,

Nilser
