<DIV> </DIV>
<DIV>I am using "all-bonds" option in order to fix all bond lengths in the system. </DIV>
<DIV> </DIV>
<DIV>However, during the energy minimization, a single C-C bond between two segments of drug changes from 1.53 to 1.80. This is the first time I faced with this kind of problem.</DIV>
<DIV> </DIV>
<DIV>How can I fix it, is anybody has an idea?</DIV>
