KeyError: 'fsleyes_pink' #120

Closed nmossazg12 closed 4 months ago

nmossazg12 commented 1 year ago

HI,

We installed fsleyes by installing the fsl in both mac and windows. When we try to open fsleyes, we receive the following error. Furthermore, even if fsleyes opens, the interface misses a lot of the features such as brightness, contrast (screenshot included below). I was wondering if you could help me figure out the issue.

Thank you OS = Windows 10 Installed the FSL using Windows Linux Subsystem (Ubuntu 20.04) `

Hi @nmossazg12, you should be able to resolve this by downgrading your version of matplotlib with a command such as:

$FSLDIR/bin/mamba install -n base matplotlib-base="3.7"

The matplotlib colormaps API has changed in the last two minor versions (3.7 and 3.8), and has broken FSLeyes on both occasions. I have updated the FSLeyes code base so that this will hopefully not happen again, but have not yet had time to release a new version of FSLeyes - I'll hopefully have time next week.

Hi @pauldmccarthy, Downgrading to matplotlib 3.7 did the trick.

Thanks
