Just download the 0.5 version, load a small pdb for a helix. It shows well in bonds, but disappears when switching to C-alphas. When I load a large pdb file downloaded from PDB, it shows fine in C-alphas.
I tried the same files with the 0.2 version come with CCP4-6.0.2. C-alphas shows well. Is there something special about pdb format from version 0.2 to 0.5? Thank you!
