Out of storage space?

2

This looks like a case of running out of space on the /tmp due to the way Unix piping is handled in MRtrix3. Lots of detail on how to handle this on this thread.

Basic summary:

  • clear out any temporary files from the /tmp folder that might have been left around after previous command crashes or interruptions. These start with the prefix mrtrix-tmp-.

  • if that’s not enough, set the TmpFileDir config file option to point to a location with more storage. The current folder might be simplest, which you can set like this:

    TmpFileDir: .
