	Dear Gromacs user


	I&#39;m currently working with Coarse grain martini forcefield, but
before that I&#39;ve used all atom simulation. in the below suggested
.mdp file [1] , as you notice the recommended value for tau-t with
V-rescale is 1 and the recommended value for tau-p with Parrinello-Rahman
is 12 but as you have remembered in Justin&#39;s tutorial this value are
set to 0.1 and 5 in order. beside, the compressibility value in
Justin&#39;s tutorial for DPPC and water is set to 4.5e-5 but in the
below .mdp file it is set to 3e-4. also Justin has answered to a person
that these value are not forcefield dependence at all. so is there any
paradox or not ? I really appreciate it if you give a direct answer to
me.


	sincerely, Ali
