Spider plugin

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

build status


You will need to use 2.0 version of Scipion to be able to run these protocols. To install the plugin, you have two options:

a) Stable version

scipion installp -p scipion-em-spider

b) Developer's version

  • download repository
 git clone
  • install
 scipion installp -p path_to_scipion-em-spider --devel

SPIDER binaries will be installed automatically with the plugin, but you can also link an existing installation. Default installation path assumed is software/em/spider-25.02, if you want to change it, set SPIDER_HOME in scipion.conf file to the folder where the SPIDER is installed. Additional information about using SPIDER with MPI can be found on a separate page. Unfortunately, at the moment we do not support MPI in our SPIDER wrappers, since it requires a lot of effort to refactor almost all protocols. :(

To check the installation, simply run one of the following Scipion tests:

scipion test spider.tests.test_protocols_spider_reconstruct.TestSpiderReconstruct
scipion test spider.tests.test_protocols_spider_align.TestSpiderAlign
scipion test spider.tests.test_workflow_spiderMDA.TestSpiderWorkflow
scipion test spider.tests.test_workflow_spiderMDA.TestSpiderConvert
scipion test spider.tests.test_protocols_spider_projmatch.TestSpiderRefinement

A complete list of tests can also be seen by executing scipion test --show --grep spider

Supported versions

In 2018 the plugin was updated to support the latest (at that moment) SPIDER version - 25.02. This required a lot of code refactoring and the support of old SPIDER version 21.03 had to be discontinued. The full changelog since Scipion-1.x is available here.
