Environment

Environment submenu.

The item allows change of Current phase in Phases, change default Directories for different file types and Instrumental parameters. Get info - shows information on the status of different control parameters and Save configuration saves current configuration into the Configuration file.

Phases

Each diffraction pattern can contain up to 10 different phases (this number can be explicitly ascribed by the program). If current phase is equal to zero then all peaks are used in all listings of profile parameters and "peak operations" in Graphics, otherwise only the peaks of selected phase are shown. Names of the phases can be given by Name phases and the current phase is selected by Select phase ( in the Main menu). All phases of the Current file are selected by Select all. The program works also without phase description (phase=0).

Change of default directories

Directories submenu
Pathnames corresponding to different file types are loaded from
Configuration file after the start of the program. They are used for example as default values for Pathname in Load file. They are automatically attached to the filenames for all I/O operations. All pathnames are listed and can be changed. If the directory name contains the wildcard '*' then the directory pick up list is shown first. (Change the directory by <Enter>. Select directory by <Esc>. Then the pathname for selected file type is changed.) The changed names are used during the whole run of the program. If you want to have the change permanent, change it in configuration file or use Save configuration item in this menu.

Change of default instrumental parameters

Instrumental parameters submenu

Change of instrumental parameters which have been loaded from configuration file. The parameters are mainly used for the correction on Lorentz, polarization and absorption factors.

Radiation:
Different X-ray tubes can be selected from the menu.
For Wavelength item the value of lambda in Å must be given and then 'Wa' is shown in the menu.

Seemann-Bohlin:
If selected, then other menu is shown connected only to the S-B geometry. First, Seemann-Bohlin must be set to 'ON'. Then also Transmission geometry can be set to 'ON'. Other parameters are described in
CONFIG.PRF .

Version

Get Info

Shows the information on the status of some control parameters.

Save configuration

Saves current configuration to the Configuration file CONFIG.PRF without comments which are included in original configuration file. Therefore it is useful to save the original file to another directory after program installation.
