Gromacs Metadata Extractor

This is the script that extracts the metadata from the molecular dynamics simulations.

This code is also deployed at https://gmxmetadump.biodata.ceitec.cz/, where it is possible to obtain metadata after uploading a TPR file without need to install or run local scripts.

Dependencies

• Gromacs software with dump utility (gmx dump)
• Python 3.8 and greater
