[phenixbb] sca file & anomalous difference map: understanding the story from the scratch,

if your input data file contains anomalous fobs+ and fobs- (or iobs+ and 
iobs-) then phenix.maps (as well as phenix.refine) will generate 
anomalous difference map automatically. All you need to do is:

1) Run phenix.maps to create a parameter file;
2) Edit that parameter file: specify input data file and labels, PDB 
file, etc;
3) Run it:
phenix.maps maps.params

This is all explained in great details here:
http://phenix-online.org/documentation/phenix_maps.htm

Alternatively, you can use PHENIX GUI to do the same thing: it is very 
easy and may be a better option for someone who is uncomfortable with 
running things in the command line, editing parameter files, etc.

Pavel.
