Cathy,
Set the ribbon_trace param to 1 to get a connected C-alpha trace, as in:
load sample_CAs.pdb
set ribbon_trace, 1
show ribbons

[PyMOL] ribbon view of c-alpha only coordinates

Dear Fellow Pymolers,

Some PDB files (notably models fitted into EM density) contain only C-alpha coordinates.
When read into Pymol, Ive found that the coordinates appear as a constellation of individual atoms, and selecting a ribbon view doesn't connect them with lines.

Anyone know a workaround to view C-alpha atom coordinates in Pymol as C-alpha traces?

thanks,

Cathy Lawson
