In tutorial A3 (MM-PBSA calcualtion), in section 1 during heating stage, you used two different temperaturre contorls, is this normal? is it enough to define only temperature variation by using :
&wt TYPE='TEMP0', istep1=0, istep2=25000,
  value1=0.1, value2=300.0, /
 &wt TYPE='END' /

Also, in Minimization stage, you minimized solvent only with a constrain on your protein-ligand? why you didn't minimzed protein-ligand complex also?
Why in the production step, he used constant pressure, not constant volume? I would appreciate if you can direct me to one reference dealing with the difference between using constant presssure or volume in the production phase.
Thanks in advance
