Backengine installation

This is a list of backengines for the implemented calculators and their installation instruction.

CrystFEL

CrystFEL is required by SimExLite.DiffractionCalculators.CrystfelCalculator.

The goal is to make gen-sfs and pattern_sim available in your $PATH.

WPG is required by SimExLite.DiffractionCalculators.WPGPropagationCalculator.

Clone the WPG repository wherever you like (e.g. /opt)

cd /opt
git clone https://github.com/samoylv/WPG.git

build WPG in your SimExLite environment

cd WPG
make

Set WPG PATH by adding this to your .bashrc or .zshrc:

# If the path where you cloned WPG is opt
export PYTHONPATH=/opt/WPG:$PYTHONPATH

or adding these lines at the beginning of your python script:

import sys
sys.path.insert(0,"/opt/WPG")
