Along those lines, one of the things you can do with PyMOL is color map density based on the color of the nearest atom (if any): Example image at: http://delsci.com/img/map_color.jpg Example script: load ref.pdb load map.xplor isomesh mesh, ref, 1.0 ramp_new ramp, ref, [0,1.5,2], [-1, -1, grey70

The crystallographic model-building and display program MIFit can read mmCIF diffraction data directly and compute the map internally i.e. you don't need any other software. There is a tutorial (lesson 16) on this exact application. MIFit runs on Windows and Linux and is free to academics users. T

[ccp4bb] CCP4i and modeller integration

2007-11-01 Thread Jayashankar
Dear friends and scientists, I want to ask about for an integration of modeller in the ccp4i interface. The interface in ccp4i is designed for modeller Version 6.2, we have by now modeller 9.2 , which is a lot different. Nevertheless I tried to enter the necessary data in ccp4i. I could not try

Dear Herman: It is due to the occupancy obviously. Previously, someone mensioned that in this resolution it is not suitable to refine the occupancy. So I think it is better for me to keep the occupancy to 1. Do you have some case for this situation in the PDB bank? Thanks. On 11/1/07, [EMAIL PRO

[ccp4bb] the B facot of soaked substrate

2007-11-01 Thread Jiamu Du
Dear All: I am refining a protein structure with a soaked substrate. The resolution is 2.5 A. The B factor of protein is around 40, while the B factor of the soaked substrate is as high as 80. The density looks fine. Is this structure acceptable? Or is there anyone who can give me an example of thi

Having put the "make my density look publishable" (mapcover) command in BobScript, my conscience wouldn't ever let me use it as it gives a false impression of experimental maps! It is useful, though, in a couple of cases: where the map is not representing electron density but calculated from th

The first 3 cif columns are not the problem. cif2mtz will happily skip these along with any other items it doesn't explicitly deal with. The problem is simply the extra columns F(+) etc, yes? This bug has been seen on Windows. The same job should work fine on Linux or Macs. Or you should be able
