A simple utility to convert cryosparc particle positions to relion star format.

Project description

A simple utility that wraps around to convert particle positions from Cryosparc JOB directories into a RELION-ready directory. On top of what already does, this script automatically symlinks (or copies) the .mrc files, renaming them as appropriate to mrcs and updating the rlnMicrographName column to reflect the change.


This package requires pyem, which is not available on pip under that name. To install it manually:

git clone
cd pyem
pip install -e .


cs2star cryosparc_job_dir [dest_dir]

A couple more options are available, check out the help page with -h.
