DIALOGBOX
- DIALOGBOX dialog_name - [field_name field_param ] | - noreturn | (n times) - separator | * Permits to construct a dialog box with editable fields. The box will appear in a window called dialog_name . The Gifa program will be blocked as long as the user has not closed the window. It will have two buttons at the button : Ok closes the form and resumes the execution of Gifa Cancel closes the form, aborts the command and generates an error The dialog box is also composed en fields which appear one on each line in the window. A dialog box can hold as many field as needed. Each field has the following general format : field_name field_type eventual list of parameters... field_name is displayed on the left side of the field field_type determines the kind of field, field_type is chosen in the following list : message, text, string, int, real, file, cursor, enum, multienum Field types are as follow: message type of field have no other field, this kind of entries serves to put plain text in the form text interprets field_name as a file name which is presented in a scrollable window. All following type have a field_var entry which determines the name of the Gifa variable in which the user input will be stored, and the default_value entry which determines the value of that variable when creating the form : field_name field_type (eventual parameters) var_name default_value string int real and file types of field have no additionnal parameters. They appear in the window as editable string. When the user hits return there, the content of the string is copied to the Gifa variable var_name. file entries will have a small arrow which permits to open a standard file dialog window. field_name cursor starting_val ending_val numb_of_digit var_name default_value cursor permits to create a sliding cursors. It has 3 additionnal parameters : starting_val ending_val numb_of_digit. starting_val and ending_val determines the edge of the slider zone. numb_of_digit determines the resolution of the slider, if 0 -> will be integer, if larger -> will be real. field_name enum/multienum enul_list var_name default_value enum and multienum permit to choose an entry into a list. enum will appear as a pop up menu permitting to choose between the entries defined in the list : enum_list. multienum will appear as a scrollable list, and several entries can be chosen from the list These field have an additional entry : enum_list. This list is a single blank separated word, each item being separated with commas. Two special entries are also available, and not associated to fields but rather to formatting the box. separator permits to enter a separator in the form, noreturn implies that the following field will be presented on the same line than the previous entry. The list is terminated with a star. The variables used by the editable entries are regular variables, that can either global or local to macro that built the dialog box. If the variable does not exist before creating the dialog box, the variable will be created local. The variables will be available to the macro after the user has clicked on Ok.

DIM
- DIM n (n=1 , 2 or 3) DIM is a context which equals 1 if you are processing one dimensional NMR spectra, 2 if you are processing two dimensional spectra and 3 if you are processing three dimensional spectra. Since 1D 2D and 3D data-sets are kept in different buffers, you can switch between this 3 modes freely, keeping the data-sets protected. related contexts : $DIM

dmxclean
- dmxclean DECIM_value DECIM is a parameter which is found in the acqus file in your data tree. This macro solves the problem of the 'additional' points on the data-sets acquired on DMX Bruker spectrometer with the digital filtering on. After applying the macro, you get an FID, on which regular processing should work, All apodisation of Linear Prediction processing will behave as usual. The macro assumes that you have acquired in SIM mode, and will work much better if you have a spectrum phased at the acquisition level. Be carefull that this macro will change slightly the size of your data-set, since the wrong points are removed. Look to the F.A.Q. at the end of the manual for details DECIM logic is adapted from W. M. Westler and F. Abildgaard
