[gmx-users] MM-GB/SA analysis in Gromacs

[andrea spitaleri]

Dear all,

I would like to bring to your attention this paper 
http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0046902 in which we made a tool 
to perform MM/PBSA binding free energy calculation in automatic fashion, using torque/pbs parallel 
system implemented in most clusters. The input of the tools are just the xtc trajectory, the tpr and 
eventually the index file. It does perform the computational alanine scanning (CAS) too. The tool is 
available upon request. Further details on the paper.


Regards,

and
