[gmx-users] some warnings

[Albert]

hello:

  I am using GBSA solvent for replica exchange simulation. However, I've 
got three wanrnigns when I generate .tpr file:


NOTE 1 [file eq_11.mdp]:
   Tumbling and or flying ice-cubes: We are not removing rotation around
   center of mass in a non-periodic system. You should probably set
   comm_mode = ANGULAR.


NOTE 2 [file eq_11.mdp]:
   Using GBSA with nstgbradii<1, setting nstgbradii=1


NOTE 3 [file eq_11.mdp]:
   Value of sa_surface_tension is < 0. Changing it to 2.05016 or 2.25936
   kJ/nm^2/mol for Still and HCT/OBC respectively


thank you very much
Albert
