cctbx.xfel is installed at SLAC for general use. Before it can be used, the following setup commands need to be run to configure the environment.

Run once

Configure pyana

Configuration files for pyana and cctbx.xfel are generally placed in a directory in your home account named ~/myrelease or ~/analisys-rel. Follow these instructions from SLAC to configure pyana.

Configure cctbx.xfel

The simplest way to configure your environment to run cctbx.xfel is to run this command (bash(1) users):

. /reg/d/ffb/cxi/temp/cctbx/cctbx_build/setpaths.sh

csh(1) users should use this command:

source /reg/d/ffb/cxi/temp/cctbx/cctbx_build/setpaths.csh

To make these changes persistent, bash(1) users are encouraged to add these lines to ~/.bashrc

test -r "/reg/d/ffb/cxi/temp/cctbx/setpaths.sh" && \
 . "/reg/d/ffb/cxi/temp/cctbx/setpaths.sh"

csh(1) users should instead add these lines to ~/.cshrc

test -r "/reg/d/ffb/cxi/temp/cctbx/setpaths.csh" && \
 source "/reg/d/ffb/cxi/temp/cctbx/cctbx-build/setpaths.csh"

Note: to avoid surprises when running cctbx.xfel from a non-interactive shell, it is recommended that bash(1) users edit ~/.bash_profile, and put this line near the top:

test -r "${HOME}/.bashrc" && . "${HOME}/.bashrc"

A job submitted to the cluster will typically run cctbx.xfel from a non-interactive shell.

Linking pyana to cctbx.xfel

Run these commands to associate pyana and cctbx.xfel together:

$ cd ~/myrelease/my_ana_pkg
$ ln -s /reg/d/ffb/cxi/temp/cctbx/cctbx_project/xfel/cxi/cspad_ana src
$ cd ..
$ scons

Run each time on logging on to SLAC

Whenever you log on to a fresh shell at SLAC, before you can use any portion of cctbx.xfel that uses pyana, you must run these commands:

$ cd ~/myrelease
$ sit_setup

Test the installation

At SLAC, test that it is working by e.g.

$ cd ~/myrelease
$ cxi.pyana -c ~hattne/myrelease/test.cfg /reg/d/psdm/cxi/cxi78513/xtc/e280-r0245-s00-c00.xtc
