Hi Danielle, The easiest way is to activate the fslpython environment first, assuming you have a fairly recent version of FSL: source $FSLDIR/fslpython/bin/activate fslpython Then try running the asl_gui script. The error you're getting is to do with matplotlib interfacing correctly to wxpython - I'm not sure if the problem is in matplotlib or wx, but either way it should work within fslpython. Let me know how you get on with this, Martin ________________________________ From: FSL - FMRIB's Software Library <[log in to unmask]> on behalf of Danielle Miller <[log in to unmask]> Sent: 01 March 2019 17:22:00 To: [log in to unmask] Subject: [FSL] BASIL issue Hi, I am trying to get the github release of the BASIL ASL software package to work. However, I keep running into the below error. I have downloaded all of the packages in parallel including matplotlib, numpy, nibabel, and wx python. Any solution this error?
