Hello, Shihai You need to realise that your problem depends on the particular pdb file. Some have a monomer, some have a multimer.
The "biomolecule" part of the command applies information contained in the pdb file to make a decision. When I do load =2B4C what I see is 4 different chains, not a trimer; you can check easily by typing color chain And load =2B4C filter "biomolecule 1" gives me the same Upon loading, Jmol console informs: found biomolecule 1: G, C, L, H found biomolecule 2: G, C, L, H And the Jmol pop-up menu lets you choose, under ""B4C" if offers Biomolecules and says biomolecule 1 has 7 thousand atoms, while biomolecule 1 has 30 thousand atoms Which one is the trimer, you will know You can always restrict what is displayed once your find out which are the chain IDs (in this case, they are G, C, L, H) display *:G, *:C ------------------------------------------------------------------------------ Full-scale, agent-less Infrastructure Monitoring from a single dashboard Integrate with 40+ ManageEngine ITSM Solutions for complete visibility Physical-Virtual-Cloud Infrastructure monitoring from one console Real user monitoring with APM Insights and performance trend reports Learn More http://pubads.g.doubleclick.net/gampad/clk?id=247754911&iu=/4140 _______________________________________________ Jmol-users mailing list Jmol-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/jmol-users
