[Neurodebian-users] fsl-5.0-gpu

> I replaced all the #/bin/sh with #/bin/bash in the bedpostx_gpu and bedpostx_postproc_gpu.sh and fsl_sub files. I think it worked now.

Excellent.

That sounds good at least.

That's odd... I greped through all of FSL's scripts, and every instance 
of zeropad is prepended with $FSLDIR; it should find zeropad. Did you, 
by chance, change that line?

Always a good idea.

The laptop could be disabling the nvidia GPU outright if you select the 
intel GPU (saving power and all). Optimus may actually be the correct 
BIOS setting. You do not want to mess with bumblebee, however, since 
that is about switching GPUs on-the-fly, which you have no desire to do 
here. You want to use Intel for display and nvidia for computing.

Sounds like things are coming along well for you!
