HI @jbcmarsman,

This may come too late to be of any use to you, but just in case:

If you have manually set your `PATH` to include `$FSLDIR/bin`, this will cause all kinds of issues – see e.g. [this post](https://community.mrtrix.org/t/mrtrix3tissue-installation-error/7156/3) for some details into the issue. You can check by typing:

```auto
echo $PATH

```

Basically, the FSL team recommends your FSL setup should be done by setting `$FSLDIR` and invoking the `$FSLDIR/etc/fslconf/fsl.sh` script – which will take care of setting up the `PATH` appropriately. You may find all it takes for MRtrix to compile properly is to rectify this…

All the best,  
Donald
