In order to get familiar with the module, here is provided a [[http://cryoem.ucsd.edu/programs/code/TestCaseLFSC.tar.gz|Test Dataset]] to download, which contains a simulated reconstruction of a ribosome (see article below for details). Specifically, the archive file contains three maps (two half maps and one map from all the particles) and a Chimera marker file with two markers pointing to two domains with different occupancy level. | In order to get familiar with the module, here is provided a [[http://cryoem.ucsd.edu/programs/code/TestCaseLFSC.tar.gz|Test Dataset]] to download, which contains a simulated reconstruction of a ribosome (see article below for details).
