no extra keywords should be needed (but you may want to look at
http://www.ccp4.ac.uk/html/cif2mtz.html for more info on these)
...tend to believe it's better to change the name of your file avoiding
the .txt extension (probably included at the time of downloading)

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.

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.

Subject: Structure factors to CCP4 maps
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
