Plugin to use Relion programs within the Scipion framework

Project description

This plugin provide wrappers around several programs of RELION software suite.

stable: stable

devel: | devel

Installation

You will need to use 3.0 version of Scipion to be able to run these protocols. To install the plugin, you have two options:

  1. Stable version

    scipion installp -p scipion-em-relion
  2. Developer’s version

    • download repository

    git clone https://github.com/scipion-em/scipion-em-relion.git
    • install

    scipion installp -p path_to_scipion-em-relion --devel

RELION sources will be downloaded and compiled automatically with the plugin, but you can also link an existing installation. Default installation path assumed is software/em/relion-3.1, if you want to change it, set RELION_HOME in scipion.conf file to the folder where the RELION is installed. If you need to use CUDA different from the one used during Scipion installation (defined by CUDA_LIB), you can add RELION_CUDA_LIB variable to the config file. Moreover, if you have to use a MPI for Relion different from Scipion MPI, you can set RELION_MPI_BIN and RELION_MPI_LIB variables in your shell environment - they will be recognized by Scipion.

To check the installation, simply run one of the tests. A complete list of tests can be displayed by executing scipion test --show --grep relion

Supported versions

3.0, 3.1

In 2020 the plugin was updated to support the latest RELION 3.1. We discontinued any support for 2.x versions. We are still working towards stable plugin release, so some things might not work yet.
