Most of operations are carried out with this file (input and output, graphics, fitting, ...) i.e. the current diffraction pattern. There are 5 files in memory. The first one is considered as a main file and is recommended for the use of the profile analysis. The others are provided mainly for comparison. Most of operations can also be applied to them, though. The current file can be selected (changed) either from the menu Files and Current File Select (where the list of files is also shown) or from the main menu of Graphics by <CTRL Fn> (n is the number of a file). The number and corresponding file- and sample names of the current pattern are shown in the bottom window of the Main text menu and top window of Graphics, respectively.
For the data evaluation the first (main) file is recommended.
