[PyMOL] Dynoplot : Interactive plot

2011-08-16 Thread Joseph André
Hi everybody,

I want to build an interactive plot I tried to use and tweak dynoplot but
DynoPlot doesn't work properly : I can display the Tk window but points
aren't plotted. However the dihedrals angles are computed correctly. There
isn't any traceback or error reported on the console.

Do you have experienced similar problems ?

My final goal is to obtain an interactive plot to show b-factor (or value
stored in b-factor column using data2bfactor) in 2D and in 3D.

Thanks.

I can confirm that DynoPlot does not work. This needs to be fixed.

Hi Thomas,

thanks for your quick reply. I'm a newbie at Tk programming but from what I
understand, gui code for Dynoplot had been written from scratch. Do you know
if they are libraries that would facilitate the plotting and the interaction
with pymol?

Best regards

Joseph

There are many libraries for plotting, for example matplotlib which is 
also shipped with recent PyMOL versions.

Dynoplot however also could update the structure by dragging dots on the 
plot, I'm not aware of a plotting library that provides this 
functionality (which does not mean that none such exists :) ).

[PyMOL] How to draw a cartoon representation on secondary structures containing beta-amino acids?

2011-08-16 Thread Baptiste Legrand
Dear all,

I have a small helical pseudopeptide with mixed alpha and beta 
amino-acids. How can I make a cartoon representation of this helix with 
Pymol? For the moment, I have selected the peptide backbone atoms and 
tried the alter command to force pymol to recognize the helix but it 
do not work.
Thanks.

Best regards,
Baptiste

 Hi all,

 Is there a direct way to load a gromacs structure file (.gro) in PyMOL? I
 know it's simple to convert them to pdb using editconf, but I want to load
 gro files directly (as you can in vmd) because they permit higher max. atom
 and residue numbers (100K vs. 10K for pdb) and permit longer residue names
 (4 chars vs. 3 for vmd).

 Thanks,
 Mike

2011-08-16 Thread Baptiste Legrand
Thanks Joseph and Thomas for your replies. When I use the as cartoon
commands, all my molecule disappear. My *pdb file could be the problem as it
is a *cif crystal structure file (converted with mercury) from the cambridge
crystal data.

 are you sure? What happens if you try this:

 alter all, ss='H'
 as cartoon
 rebuild
