<div>Dear Elaine C. Meng, Ph.D.,</div><div><div>Thank you very much for your suggestion.</div><div>Currently, there are not many people using chimera software in China. This is because the professors are using PyMOL, so the students do not have a good understanding of the ease of use of chimera software. I am translating and promoting the basic manual of chimera software. I look forward to more people knowing and using this software in the future.</div></div><div>Thanks again for your help!</div><div><div style="text-align: right;"><div>Zhuangwei zhang</div><div>Zhejiang Oeacn University</div></div></div>

Hi Zhuangwei Zhang,<br>Chimera is not doing any "recognizing," this is just because you have the protein and peptide in two different models because they were opened from two different files. This output PDB file has them as two models, which is OK for many programs. However, If you want to write a PDB file where both structures are in one model, you have to first combine them. <br><br>In Chimera you can combine models with the "copy/combine" function in the Model Panel (open Model Panel from Favorites menu, choose the two models on the left, i.e. highlight both rows with the mouse, then click the "copy/combine" button on the right, OR you can use the "combine" command.<br><br>copy/combine in Model Panel<br><https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/modelpanel.html#combine><br><br>combine command:<br><https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/combine.html><br><br>Then just save the new combined model as a PDB file.<br><br>I hope this helps,<br>Elaine<br>-----<br>Elaine C.
