Re: [COOT] Structure factors to CCP4 maps

[RiC]

I am NOT trying to open the CCP4 file on a text editor !

I am trying to do the following on CCP4/COOT:

 1) Download a PDB  (example 1c75.pdb) from the PDB database

2) Download the corresponding structure factors (example 1c75-sf.cif.txt)

3) Now from the above sf-cif file How can I get a MTZ file using  CCP4

4) Then display the map (either in CCP4 format or MTZ format) in COOT

I want to know how to do step 3 above.

Sorry, I was not more clearer earlier.

Patrick

I am terribly sorry, but ccp4 maps are understandable to nobody.  They are binary files, for starters.  Even if you develop an uncanny ability to read these you will still be left with random looking sea of numbers.

If you trying to generate a model map, you can use sfall.  Given that you are posting on coot bb, the easiest way to visualize such map is to use Fc column from, say, zero step refmac run.

Be more specific.  Look at pdb_redo, it may be what you are looking for.

HI,

Does anyone have a step by step guide to go from a structure factor file from the PDB to a CCP4 map (understandable to a biologist)  like the one I can download on the electron density server?

I am confused and my attempts at using CCP4 keeps coming up with "failed"

Thanks
Patrick
