Hi Pascual, The PDB file does not really have information on bonds. If atoms are closer than some cutoff a bond is drawn. Unbonding and saving will not change the distance, so the bond will be drawn again when loaded again. What is your aim? Cheers, Tsjerk On Tue, Jan 19, 2016 at 12:15 PM,

Well, yes, programs do use the CONECT records, including pymol http://pymolwiki.org/index.php/Connect_mode Removing bonds is http://pymolwiki.org/index.php/Unbond Atoms can be translated using the command line http://pymolwiki.org/index.php/Editing_atoms#Get_coordinates_from_Python Or in edit

CONECT records are not used for peptide bonds for standard amino acid and nucleic acid links. These are assumed. In addition, for these standard chemical component, CONECT records are not used to internal bonds - they are "known." Non standard amino/nucleic acids used CONECT records for all

Thanks, David! My take- Pymol is a very powerful tool for creating beautiful and insightful figures of molecules, with myriad features for displaying aspects of interest to structural biologists, such as different surfaces, electrostatic potential, H-bonds and other inter-atomic interactions,

Hi Edward, Oh, I read over the moving part. Well, what I meant to convey is that you can use CONECT records to draw additional bonds, but for the rest bondedness is inferred from distance. So you can only remove bonds if the particles are further apart than the cutoff AND have a CONECT record.

[PyMOL] segmentation fault

2016-01-19 Thread henry tang
Dear developer, I had this segmentation fault problem whenever using plugin like apbs or autodock etc. it crashes when I click button "APBS binary location" etc, Tried both pymol 1.7.4 and 1.8.0 and gave the same error. Any help would be greatly appreciated. Detected OpenGL version 2.0 or
