xgen [--help] [--version] [--commands] [-hvc] [command]
"xgen" is a command-line interface to the X-GEN software. It and "xgen-
tools" replace roughly one hundred executables, each of which was
intended to perform one particular function and then exit. "xgen" and
"xgentools" are structurally identical software packages; the only dif-
ference is the list of functionalities that are accessible from them.
"xgen" provides access to the fifty most important functionalities
within the package; "xgentools" offers access to about fifty less uni-
versally-required functionalities. The only users who are likely to
require "xgentools" are facility managers and developers.
In one-line mode, the user executes a single X-GEN command and then
exits. In interactive mode, the user types "xgen" and is greeted with
a prompt, "x> ". The user then can type in either X-GEN commands or
shell commands, including commands like "POLARIZATION_TYPE=3" and
"source *.com". Filename expansion is accomplished in both cases.
As we have said elsewhere, X-GEN provides for data processing, begin-
ning at raw images and ending at the creation and analysis of an ASCII
file containing h,k,l,F,sigma, and some anomalous information. In
between it enables
* determining the pixel-to-centimeter mapping of the detector;
* finding the active area of the detector;
* finding a set of reference spots for indexing
* finding a set of reference model profiles for profile fitting;
* auto-indexing the data, if needed;
* refining the unit cell and orientation;
* integrating the data,
i.e. determining intensities by profile-fitting and simple summation;
* filtering the integrated data;
* merging multiple data runs;
* scaling the data;
* eliminating outliers;
* determining statistical parameters associated with the data;
* obtaining the ASCII (h,k,l,F,sigma,... ) information.

tions of environment variables, e.g. "POLARIZATION_TYPE=3"; and sourc-
