[gmx-users] perfluorohexane pdb... again

[Marcelo Silva]

Thank you Angél and Stephane for your help

I also have another question. Using the pure hexane pdb (I am mixing 
hexane and perfluorohexane), I've run simmulated annealing with a box of 
500 molecules trying to obtain a good conformer distribution. The 
heating steps were:

time (ps): 0  8 50 58 150
Temperature: 298 1000 298 1000 298

I don't if this is the best temperature program but I've converted the 
trajectory to a pdb file (last time step) and using Avogadro I see a box 
full of hexane molecules but the same conformer. Using Rasmol I see 
different conformers and the box as several holes in it. What is wrong 
here?

Thank you again and best regards
