Re: [PyMOL] [Apbs-users] Strange behaviour with APBS

Nathan, Strictly speaking, the issue may be with PDB2PQR itself, not APBS. Furthermore, we don't yet know whether a combined development version of all three packages would still reproduce the problem. As an aside, a good reason for PyMOL to see PQR files is for diagnostic visualization: to enab

Hi Warren -- The PQR format (which doesn't really have a standard) is basically just whitespace delimited. I'm curious, though -- why would a PyMOL APBS invocation ever see the PDB file? Wouldn't a user first convert it to PQR with PDB2PQR (ideally) or with PyMOL's built-in functionality?

Joachim, The trick with that is the same as in real life: you must place the camera the same distance from each object you intend to photograph. But how can we do this with PyMOL? Ah ha! I've got it The "center" command positions and points the camera at the molecule. center object-name And

Gilles, The PyMOL and APBS programs have differing views as to whether PDB & PQR files are column-based or space-delimited, respectively. We must eventually sort this out, because it causes continued grief for our users in common. For now, however, the workaround is to make sure no B-factors exc

Hallo, we want to create a set of pictures from different molecules but the zoom value should all be the same. ANd is there an easy way to zoom in or out by e.g. 5%? -- Joachim

[PyMOL] Strange behaviour with APBS

2008-09-17 Thread Gilles Truan
I have noticed a strange behaviour of the APBS module. I used it a lot recently and it works perfectly for 95% of the structures I analyzed. I usually fetch the pdb code, then remove waters, heteroatoms and so on. I also noticed that in some cases, when the b factor is quite big (over 100) APBS
