Hi people.
Well, this thread is going to become an independet list for ILs.
We have developed a force field for a small set of cations and anions of
ILs, few year ago, based on AMBER. At the moment, we are (slowly) finalizing
publications on the extension of those for new sets of anions, all

Thanks again, Mark! Your comments made me realize that I was mixing two concepts

Hi!
I am just wondering that why the potential energy couldnt be positive? It must
have been negative after minimization at 0 K, but in the simulation at specific
temperature the energy of the intramolecular interactions increases increasing

Now, what could this mean? This actually means, in the forcefield

Hi
You have to tell GROMACS in the parameters-file (.ppa) which kind of PMF
you want to calculate (runtype=afm,umbrella). Depending on this choice
it's very likely that the afm_rate is simply ignored for umbrella, no?
The force constant is mimicking the stiffness of the spring. You want to

Thank you for the suggestion !
Originally, there were about 250 residues.
"182 residues" might be from the end-index of
'r_81_r_82_r_83_r_102_r_111_r_149_r_178_r_182' .
Do I make wrong index file ? or, is the result-file normal?

Hi,
Well, think harder about your 'problem'. How hard can it be to solve
all terms to reach the nearest local minimum for a system of 36 atoms?
You could basically do it by hand! No wonder that you reach
convergence to machine precision in 14 steps. Check the archives on
