Hi Justin, I read the manual and it mentions how to specify QM/MM parameters, but no detail is provided. Also it says 'GROMACS provides interfaces to several popular Quantum Chemistry packages', but I'm not very clear about what does 'interfaces' mean. According to my understanding, if we want to c

Hi Zhenyu, yes, I see this behavior every time a site is buried within a large structure, say a micelle or a lipid bilayer. RDF profiles yield the PMF profiles between the two species, so a value below unity stands for a repulsive region (in the thermodynamic sense, not in the mechanical sense) a

Hi Aniko, Another option is to use a HERE doc such as: gmx something << HERE 0 1 HERE which would execute the gmx command and give it as input: 0, a return character, and then 1 (with a return character also). Check the advanced bash-scripting guide for more details: http://tldp.org/LDP/abs/
