Crystals PrimerChapter 4: Basic Data InputCRYSTALS has powerful reflection processing features,
described in the Reference Manual. A simplified input is available if
the
user knows the unit cell, space group, molecular formula and has a file
(e.g. REFLECTIONS.DAT) containing reflections in the form h, k, l, Fsq,
Sigma(Fsq),
one per line.

\QUICKSTART
\SCRIPT QUICKST
Use QUICKSTART for normal situations. This command requires minimal user input, and sets up the basic data lists in the data base. See the manual for a description of the lists created, and how to deal with complicated cases. Permitted reflection data types are Fo, Fsquare, and I. The Lp correction for 4 circle geometry is applied if the type is I. LIST 28 sets the minimum value of I/sigma(I) to be used in calculations. \SCRIPT CADQUICK
\SCRIPT CADSLOW
These SCRIPTS takes as input the files produced
by the CAD4 data processing program RC93 (or RC85).
