iMars3D 3D reconstruction software for neutron imaging

Run

• Create a directory for the reconstruction, and cd into it

$ mkdir -p ~/recon/turbine
$ cd ~/recon/turbine

• Create a recon script:

#!/usr/bin/env python
from imars3d.CT import CT
ct = CT("path")
ct.recon()

Remember to replace path with the path to the CT data directory (which contains WB/DF/CT data)
