WebDec 10, 2014 · I realize that the charmm CMAP potential is not currently supported for HREX to do REST. However, I wonder if this lack of support means only that the cmap section of the topology files are not processed by "plumed partial_tempering". If this is the case, then I can figure out how to scale the cmap section myself after I have used the … Webnotably, however, it is shown that the use of the CHARMM CMAP (31,32) backbone potential allows some many-body effects to be included in the additive force ﬁeld, …

WebFeb 17, 2014 · CHARMM's "autogenerate" does not generate CMAP terms; those will only be applied if there's a CMAP entry in the topology. In which case CHARMM indeed uses the atom types to figure out which map to apply. I would be highly surprised if the psf format wouldn't have a similar mechanism to explicitly signal the presence of a CMAP term. WebOct 19, 2024 · The 'psfgen' plugin reads standard PDB files, Charmm topology files, and PSF files in X-PLOR/NAMD format. Psfgen will accept PSF files using the Charmm CMAP cross-term map force field extension. Psfgen does not currently support Charmm PSF files using the Charmm 'EXT' expanded format, but will updated soon. overclock dell optiplex 7010WebMar 4, 2014 · I did apply existing CMAP to the NH2 terminus, but the population in the alpha_L conformation for LEU is significant, which doesn't seem right. Without CMAP, the conformation is much in alpha_R state, which apparently is an overestimation. Any suggestions?
