[gmx-users] A problem about genbox

[zhengbs at jlu.edu.cn]

Dear gmx-users:
I am using genbox to solve a protein modeled by modeller.After pdb2gmx and editconf,there are 335 residues with 3204 atoms,and box size is 6.103 * 6.196 * 6.546.Then i  " genbox -cp out -cs -p APE1547LID -o b4em ",when it progressed to 
" GRoups of Organic Molecules in ACtion for Science
  Containing 3204 atoms in 335 residues
  Initialising van der waals distances...
  Reading solvent configuration
  ""
  solvent configuration contains 648 atoms in 216 residues 
                                                   ",the cursor is flashing but program was seemed not to move on.Is it too big for gmx to generate a box for this protein,or it will take a long time?

Thanking in advance
