XDisplayF (xdisp) allows to visualize X-ray data in original form, obtained from X-ray detector as well as observe the progress of data integration. This visualization is very important to monitor the correctness of X-ray data prediction and integration processes as well as quickly adjusts some integration parameters, like mosaicity, spot shape and size.

Please note, that XDisplayF is x-window program and it is necessary to have X-Window support. Because xdisp use the x-window interface it is possible to use remote computer as a host computer.

Starting XdisplayF (xdisp)

XDISP in an alias for running XDisplayF program. Simplest way to run this XDisplayF it is necessary to type next command string:
xdisp FORMAT Image_Name, where
FORMAT is the format of the X-ray data image. All supported by xdisp formats are listed here: Formats supported by xdisp. It is possible to have a list of all supported programs by typing in the command litne xdisp.
Image_Name - Name of the X-ray data image with path to this image.

Another options to run xdisp

It is possible to launch the program with the Image_Name specified with variable number, according to standard numbering scheme.
xdisp FORMAT Image_Name###.ext number - in this case the sign ### will be substituted by number.

xdisp FORMAT Image_Name###.ext number Image_Name###.x
- in this case the sign ### will be substituted by number.
- Image_Name###.x - List of integrated reflections from Denzo output. In the ImageWindow you can click "Update Pred" and prediction will appear on the screen.

Communication between xdisp and Denzo

Denzo and xdisp communicate between each other through the hklprediction ans .test files, that is why it is necessary to use the same directory to run Denzo and xdisp.

XDisplayF (xdisp) window description

After proper running xdisp the window with image will appear. The name of the image will be on the top of the xdisp window. Here you can read description of all buttons and outputs in the xdisp window. Despite this full description it is much more useful to became more familiar is to play by yourself with this xdisp window. In case if everything goes wrong - just kill this window by clicking close button and rerun the XDisplayF program again.

HKL2000, xdisp top part of window

This is a top part of the XDisplayF program window. Please note, that the button alignment on this window is depends from the image displayed. At the top part of window, the image name is displayed.

Prof fit R hkl2000, XDisplayF, xdisp: prof fit r

Allow to turn on/off the profile fitting radius. This function is working when the prediction is already done. The only spots stronger than WEAK LEVEL, according to Denzo are shown. For definition of PROFILE FITTING RADIUS refer to the Denzo manual. These two X-ray diffraction pattern with prediction shows the xdisp window with and without Prof fit R:
