However, one thing you might try in Chimera is to delete all the hydrogens and then add them back before running the Audock Vina tool, for example, commands:</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>delete H</p><p class=MsoNormal>addh</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Also please understand that Autodock Vina is running on a web service outside of Chimera, so the messages in the log are from that separate program (not from Chimera directly); in other words, I don’t have any deeper understanding of the messages, I can only repeat what it says in the log. Besides the ligand hydrogen error, there is also a warning that your search box is very large, so you may want to make that box smaller. It says “see FAQ” which is the Autodock Vina FAQ at Scripps:</p><p class=MsoNormal><http://vina.scripps.edu/manual.html#faq></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>You do not need to make the box go around the whole receptor, only around the possible binding site.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I tried docking some simple test ligand of my own against 1sj0, the same receptor you were using, and it ran without any problems.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I hope this helps,</p><p class=MsoNormal>Elaine</p><p class=MsoNormal>----------</p><p class=MsoNormal>Elaine C.
