I am using ChimeraX to do some mutagenesis in the protein with its 3D structure. After mutagenesis, the clashes were found. I tried to use tool torsion to adjust the atoms' angles and found when one clash was solved the other clashes came up. It seems it is a endless process. The question is how to correct the clashes due to mutagenesis, only manually adjust one by one using tool torsion or there is other ways to do in the same time simutaneously, such as using modeller inbeded in ChimeraX?</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Thanks very much for your help</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Sincerely</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Tiger Wang</div></div></body></html>
