Excuse me:

Thanks for your good tool.I'am a student studying bioinformatics.I have met a trouble.My PDB file created by a protein—protien docking tool ZDOCK.It can not opened by Chimera.But can opened by Jmol and DS ViewerPro Trial.While the graphic created by Chimera is more beautiful.
One of the PDB file is in the accessory.

Thanks
