Dear Chimera developers：

I have a problem in using Chimera！

I want to save a ligand-receptor complex file for further analysis，but I can not save a such PDB file！You can see the figure below！

The target was protein, and the atr_1 was the ligand, all files were saved from the dock results of Swissdock online tool (figure 2)!

I hope you can help me, thank you very much!

Best wish,

Jianan Li
