The inputs and outputs of the simulations, principally consisting of PDB files representing flexible variations on the protease crystal structures, are available for download from the University of Bath research data archive at https://researchdata.bath.ac.uk/772/ [11] with DOI https://doi.org/10.15125/BATH-00772 Output data: the inputs, scripts and outputs of the rigidity analysis, normal mode analysis, and geometric simulations for each protein have been deposited in the University of Bath’s data repository and are accessible from https://researchdata.bath.ac.uk/772/ [11] [11] Wells, S.A., Dataset for "Rigidity, normal modes and flexible motion of a SARS-CoV-2 (COVID19) protease structure". 2020.
