According to the lysozyme model in the tutorial of Justin Lemkul in http://www.bevanlab.biochem.vt.edu/Pages/Personal/justin/gmx-tutorials/index.html, I am runing a 2 chain protein complex MD, and the steps are exactly same as in that on-line tutorial except that I use the 2 chain protein rather than laysozyme. In the preparation steps, GROMACS produces 2 *.itp file,ne for chain A, one for chain B. But in the following steps, I find the 2 *.itp files have never been used by the following command. Thus sometimes I am suspicious for the following steps whether the MD was done only on Chain A or on both Chains.
Will you please clarify why GROMACS produces the 2 *.itp files but never used them in the following MD steps? Have I done something wrong on my 2 chain protein MD?
I am looking forward to getting your reply.
