Compute Canada systems can be used for visualization as well as computation.  We have installed the MINC toolkit with the graphical pieces (Display, register) included on the Graham system, allowing you to view files created there without first transferring to another system.  You can also use R to interactively make and view plots (although fitting models, reading large numbers of files, etc., should be done on other nodes; see the references), and Compute Canada provides a number of other visualization tools such as Paraview, VisIt, etc. which you may find useful for visualizing cortical surfaces, point clouds, deformation fields, etc.

Our suggested methodology is as follows:

  • get a Compute Canada account if you don't have one (you need a PI identifier; see your PI, or Ben if you're in Jason's group)
  • start a VNC client on your local machine (e.g., laptop, MICe desktop).
  • point your client towards gra-vdi.computecanada.ca and log in using your Compute Canada login name and password (used for both logging into the computecanada.ca website and CC systems).  Note: you seemingly can't ssh to this address.
  • module load minc-toolkit/1.9.17-visual-tools
  • use Display or register as usual (no need to use vglrun)

The CC reference docs below propose other ways of doing visualization.  Please update this page if you attempt any!
