Installing GSAS-II via conda (Anaconda Python)

Python enthusiasts are likely quite familiar with the Anaconda package manager. GSAS-II can be installed using the following command conda command after installing anaconda or miniconda. Note that Python 2.7 or 3.6+ can be used, but not all platforms/combinations have been tested. Use This command to install GSAS-II:

conda install gsas2pkg -c briantoby 

If you get an error that conda is an unknown command, this means anaconda/miniconda is not in your path (which is my recommended way to install anaconda) and you will need to first use the ananconda activate command:

mac/linux:

source <condapath>/bin/activate

windows:

<condapath>\Scripts\activate

After the conda install completes, one of the following occurs:

  • On the Mac, an app is created that can be dragged to the doc (or create a shortcut to GSAS-II.app and drag that anywhere).
  • On Windows a desktop shortcut is created.
  • On Linux (at present) the command-line is needed to start GSAS-II:
    <condapath>/bin/python <condapath>/GSASII/GSASII.py
    

This mechanism is a new installation option (as of June 2018) and feedback on problems or suggestions on how to make this better integrated with anaconda are solicited.

GSAS-II Updates

Note that updates to GSAS-II are not integrated into conda and are not coupled to the specific versions of Python packages you have loaded. To obtain the latest version GSAS-II (you are strongly recommended to update regularly) use the Help/Update menu command or rerun the bootstrap.py script using this command:

<condapath>/bin/python <condapath>/GSASII/bootstrap.py
