<div dir="ltr"><div>Thank you guys so much for the suggestions! I don't know why I still have rotamer outliers after real-space refinement. I am wondering what might go wrong and what I should check in this case? <br><br>
At the same time, I fixed the Ramanchandran outliers and rotamer outliers in Coot, and did another refinement with default setting + NCS restraints + secondary structure restraints + optimize X-ray/ stereochemistry + optimize X-ray/ ADP. Are these refinement settings look reasonable to you? <br>
Below are the results:<br></div><div>R-work: 0.2542, R-free: 0.2857, Angles: 1, Bonds: 0.003. <br>
Ramachandran outliers: 0.4% (Goal: <0.2%), Ramachandran favored: 92.6% (Goal: >98%).<br>
Rotamer outliers: 0 % (Goal: 1%), c-beta outliers: 0 (Goal: 0)<br>clashscore: 6.92, overall score: 1.85. <br></div><div>But, when I opened the results in coot, do Ramanchandran plot, and I couldn't see any Ramanchandran outliers. <br>
<br>Let me know any comments or suggestions about what to do or check next. Thank you so much!<br><br></div><div>Best,<br>Wei <br></div><div><br></div><br></div>
