  Thanks for your reply!
   
  When I plan to run MD on the whole system of the receptor-ligand,usually, firstly I want to use antechamber to obtain the ligand.prepin file and ligand.frcmod file. Then I can obtain the .prmtop and .inpcrd file of the whole complex in Xleap/tleap.
   
  Now, if I save the ligand using mol2 format and save the receptor using the pdb format, how can I save the receptor -ligand in a file and run the MD on the whole complex? Maybe I misunderstand your suggestions. Can you more explicitly elaborate your advices or methods please? I am really interested in your suggestions!
   
  Thanks for your suggestion again!

  Also, if you have Sybyl software and use it to prepare files for Amber
calculation, it can be easier to keep mol2 files for ligand and pdb
format for receptor (if it is a problem receptor - ligand)...
