add new patch for fsl 6.0.4 asl_gui bug
problem:
fsl-6.0.4 asl_gui was shipped with a broken fsleyes preview panel. People downloading this version if FSL are not able to use the asl_gui. We need to patch the gui code to fix this error.
Solution:
update the fslinstaller.py script
- detect if the downloaded FSL version is 6.0.4
- if so, patch $FSLDIR/python/oxford_asl/gui/preview_fsleyes.py
- if any other FSL version do nothing.
Procedure:
- download and install fsl 6.0.4 with the installer script.
- after all files have been moved to the correect locations patch the asl bug in the post install routine
