To maintain FAIR data principles and be good stewards of generating high-quality, accurate MD simulation, all input files, parameter files, and key structural snapshots from the simulation should be shared. Sharing partial datasets in unusable file formats, such as only providing ligand topologies in a PDF, limits others' ability to reproduce the work and 11 ensure accuracy of the simulation performed. To adhere to the FAIR data principles, researchers should provide complete input files in usable (and machine-readable) formats, such as .pdb/gro, .top, and .mdp for GROMACS or .pdb/crd, .psf, and .inp for CHARMM and NAMD. These files should include full system topology, force field parameters, and configuration settings. Doing so helps to address challenges in storing metadata associated with the simulations themselves, including algorithms used and force field terms. Repositories such as GitHub, Zenodo, MDDB, and MDRepo 40 offer structured platforms for sharing these data. Tools such as Martignac 41 are a model for how to "work backwards" from existing simulation data to determine how simulation systems were prepared, and additional effort should be placed on developing such tools. Proactive planning in terms of data sharing and reuse will facilitate resuability over time.
