Crystallographic Data Files

[faysunKle]

WHICH TYPE(S) OF FILES SHOULD I USE (.mmCIF, .CIF, .mtz or other)   WITH WHICH PROGRAM(S)     (FREE OF CHARGE; for example COOT,CCP4,PyMOL ) TO PLOT ELECTRON DENSITY MAPS LIKE SHOWN IN THE ATTACHED FILE:  FIGS. 1 AND 2.

 

IF I AM NOT MISTAKEN THESE ARE ONLY OBTAINED FROM CRYSTALLOGRAPHIC STUDIES. 

ALSO IF THERE ARE PUBLIC DATABASES WHICH HOLD EVEN THE VERY FIRST RESULTS OF CRYSTALLOGRAPHY, THE PICTURES THAT SHOW THE SET OF SPOTS ON THE FILM PLATE THAT CAPTURES THEM LIKE SHOWN IN FIG. 3.

 

I AM INTERESTED FOR THE SIMPLEST OF COMPOUNDS AND SINGLE ELEMENTS THAT CAN BE USED IN CRYSTALLOGRAPHY. THE WEB IS FLOODED WITH COMPLEX COMPOUNDS LIKE PROTEINS WHICH ARE OFF COURSE OF PARAMOUNT IMPORTANCE TO SCIENCE BUT HAS VERY FEW IF I AM SEARCHING CORRECTLY ON SIMPLE COMPOUNDS AND ELEMENTS.
