I realized that these Tinker's stretch-torsion and angle-torsion coupling forces are not present in openmm and thus, it's not possible to use OpenMM-Plumed combination right now for nucleic acid simulations. I am just curious is there any near future possibility that these forces will be included, t...

Thanks again for the suggestion. I have run the script and it works as you suggested. But, I think script is missing conversion of parameters associated with phosphate groups mainly "strtor" and "angtors". I am unable to find the conversion of these terms to openmm format. If you can point me to som...

Thanks for your reply. I would like to modify the suggested script. I saw this script before but I am not sure how to use it. Please is it possible to provide some suggestions on correct usage of this script? Also, if possible, could you please point out the suspected changes that I should keep in m...

Hi all, I am a new user to openmm as well as tinker-openmm softwares. I wish to use recently published (DOI: 10.1021/acs.jctc.7b01169) nucleic acid AMOEBA parameters using only openmm-plumed combination. But I am unable to find way for conversion of new tinker parm file to xml format. some of the ol...
