Edit and run

Viewing stuff in chemview is fairly easy. But since it deals only with visualization we will use another program (mdtraj) to pull data from the web. This is a protein.



In [1]:

    
import mdtraj as md
traj = md.load_pdb('2M6K.pdb')
print traj









    



<mdtraj.Trajectory with 30 frames, 4462 atoms, 292 residues, and unitcells>

Chemview provides a class MolecularViewer and helpers to let you easily display the protein using a cylinder and strand representation.



In [4]:

    
from chemview import MolecularViewer, enable_notebook
from chemview.contrib import topology_mdtraj
enable_notebook()

mv = MolecularViewer(traj.xyz[0], topology_mdtraj(traj))
mv.cylinder_and_strand()
mv
