I think you need to look at the literature about things like this- we
can help with technical issues, but you really need to know what, if
anything, others have done before you try something extremely
challenging like this. monomer-dimer equilibrium is likely well beyond
the timescale of 2ns, or even 2 microsec. for any new project I
strongly encourage you to read the literature and see if it has ever
been done before, and if yes you can use that work as a guide. if no,
expect lots of trial and error as you go forward. as you run into
technical problems, ask about them here. it won't substitute, though,
for needing a thorough literature search first.
