Re: [PyMOL] about Display CCP4 Maps
Hi Lina, Could you be more specific about what you are trying to do. E.g. I have a structure from the pdb and I would like to display the density. If it is this option then you can automatically generate ccp4 type maps from http://eds.bmc.uu.se/eds/ assuming the structure factors have been deposited. You can them load these into pymol (file.ccp4) Or I am determining the structure of a protein ligand complex and I wish to calculate the electron density map . If this is the case I would suggest some further reading of the ccp4 tutorials. These come with ccp4i Hope this helps Joel _ Joel Tyndall, PhD Senior Lecturer in Medicinal Chemistry National School of Pharmacy University of Otago PO Box 56 Dunedin 9054 New Zealand Skype: jtyndall http://www.researcherid.com/rid/C-2803-2008 Pukeka Matua Te Kura Taiwhanga Putaiao Te Whare Wananga o Otago Pouaka Poutapeta 56 Otepoti 9054 Aotearoa Ph / Waea +64 3 4797293 Fax / Waeawhakaahua +64 3 4797034 -Original Message- From: lina [mailto:lina.lastn...@gmail.com] Sent: Wednesday, 26 October 2011 1:27 a.m. To: Thomas Holder Cc: pymol-users@lists.sourceforge.net Subject: Re: [PyMOL] about Display CCP4 Maps On Tue, Oct 25, 2011 at 7:56 PM, Thomas Holder spel...@users.sourceforge.net wrote: Hi Lina, do you already have any electron density or reflection file (*.map, *.mtz, ...) or do you want to create a fake density from your structure?

Re: [PyMOL] about Display CCP4 Maps
Lina, If you want to create an "omit" map for your ligand using CCP4i, you can find instructions here for both Fo-Fc and 2Fo-Fc maps: http://capsicum.colgate.edu/chwiki/tiki-index.php?page=Model+Building+and+Validation#Creating_Omit_Maps_for_Ligands_using_Refmac To display an omit map in Pymol around your ligand, you can find instructions here: http://capsicum.colgate.edu/chwiki/tiki-index.php?page=Visualization+of+PDB+files#Visualizing_Electron_Density_Maps These last instructions are the same as those I posted on the CCP4 wiki. http://capsicum.colgate.edu/chwiki/tiki-index.php?page=Visualization+of+PDB+files#Visualizing_Electron_Density_Maps __ Roger S.

Once the map is loaded into PyMOL you can choose how you want to represent the data: isomesh, isosurface, slice, gradient, or the new volumes. To make a new representation for the map choose one of those from the A (Action) button. 2] For small molecular (ligand), the ccp4 is the best way to obtain its electron density map? PyMOL natively reads these maps, so you don't need ccp4i or any special plugins. At present I have problem created the map.
