attached is a tar file that contains TFE parameters. also included are charmm22 protein toppar files and example inputs. the TFE parameters are in a toppar stream file that requires a special version of the protein toppar files that includes our revised LJ parameters for the alkanes. the test cases will give you an idea how to use the stream file.

I am interested in the TFE-parameters, as well. Unfortunately, it really seems that the attachment sent to Idemaria containing these parameters got deleted - would it be possible to have the attachment uploaded again (see request of hlwood)?
Dear "Parameter-Gurus", I used the (Jan '04) TFE parameters kindly provided by Alex M. for simulation of a 80% (v/v) TFE/water-mixture. There seem to be too little TFE-TFE interactions/H-bonds as compared to experimental data(e.g. J.Phys.Chem. A 2005, 109, 7667-7676) probably resulting from wrong F-atom parameters. Is anybody working on a new optimization of CHarmm TFE parameters ? Maybe I could join this effort based on our experiences with different boxes @ various TFE/water ratios (e.g. 4%, 20%, 40%, 60%, 14%, 30% and 80%[v/v]) mixtures. best regards, David
I am attching the pdb of ligand coumarin infact I wish to try with charmm(academic) fo this to create top and param files, as i saw the Example top and param for TFP- drug like molecule, it was split up in to several molecules and then at the end top file are created, similary how could i split my molecule to create top file accoding to the available charmm sources. thanking you
