Segmentation fault with mrtrix3 commands (eg, mrgrid -h)

Hi @chand671,

To diagnose this, we’re going to need a lot more information. Can you tell us:

  • were things working at any point? Maybe the problems started after a system update or something?
  • was this compiled from source, or installed as a precompiled package (via anaconda)?
  • if from source:
    • are all your system packages up to date?
    • can you post the full contents of your configure.log & build.log?
    • can you try to narrow down where the segfault occurs, using the instructions on the debugging wiki?
  • if via anaconda:
    • is anaconda up to date?
    • do you see any errors related to libtiff?

Thanks?
Donald
