Spider plugin

This plugin provides wrappers for several programs of SPIDER software suite.

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-spider

2. Developer's version

   • download repository

   git clone -b devel https://github.com/scipion-em/scipion-em-spider.git

   • 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-26.06, 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. :( Depending on you CPU type you might want to change the default binary from spider_linux_mp_intel64 to a different one by explicitly setting SPIDER variable.

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
