does gromacs support reaxff? no! so why does it matter to the gromacs

how should they get in there? and why should this be done with
analysis tools for a simulation package that doesn't have a need for

this statement is for the most part just buzzwords without any
specific meaning. to give them meaning you have to figure out which
specific indicators can be used to draw conclusions from your
simulations. as i stated before, these kind of considerations
typically have to be done when planning your simulations. running the
simulations itself is usually the simplest task. and for something as
unusual as reaxff, you have to be prepared to write your own analysis
tools. or search if there are analysis tools or at the very least
preprocessing tools to be used for the simulation package you use.
this is now getting extremely off-topic for a mailing list on VMD, so
lets close this topic.
