[Chimera-users] problem

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 Jianan Li-Harbin Medical University 364453372@qq.com
