Dear xtb users,
an updated version of the xtb code version 6.1beta can be downloaded.
See the release notes for details.
The version mainly contains bug-fixes, AMD proc support (hopefully working), and as a very cool new feature Cartesian RMSD based metadynamics (MTD(RMSD)) for doing nanoreactor simulations or finding reaction paths.
I was also able using this technique to significantly improve our conformer search algorithm. See the chemarxiv preprint for details (https://doi.org/10.26434/chemrxiv.7660532.v1).
The GFN2-xTB can also be cited (10.1021/acs.jctc.8b01176).
The new conformer search procedure is implemented fully OMP parallel in a code dubbed CREST (Conformer-Rotamer Ensemble Sampling
Tool)
which can be downloaded as well. The old MF-MD-GC version is still available.
Again: this makes the widely used -siman option totally obsolete as crest is much better, very well tested, and save regarding the ability of finding really good ensembles including the right lowest-energy conformer. For more info just type crest -h or simply crest in a directory with valid "coord" file.
The new scheme will be our default also in the fully automatic NMR spectra calculation procedure. The NMR related codes enso.py/anmr will be updated very soon.
Best
Stefan Grimme (and the development team)
