Instead, we do it the long way by simply calculating the RMSD of each frame in the second trajectory, to each frame in the first trajectory. iowa state dan thomson

"WebSep 27, 2024 · Author: Jared Adolf-Bryfogle ( [email protected] ) This metric calculates the RMSD between the input and the set comparison pose. You may use the cmd-line native if the option use_native is true. Default is to calculate all_heavy atoms - but this can be set using the option rmsd_types. We match all corresponding atoms for each residue to match. " - Select group for rmsd calculation
