Hello,<br><br>I am performing protein-ligand docking simulations, and the preferred ligand input file format is Mol2.  I obtained some of my ligand structures from PubChem in SDF format, and I noticed that the SDF files contain partial charges (&quot;PUBCHEM_MMFF94_PARTIAL_CHARGES&quot;).  Is there a way to preserve the charges in Chimera when converting to Mol2 file format?<br>
<br>Thanks in advance.<br><br>Nancy<br><br><br><br>
