 DBCLOSE 
 
 

DBCLOSE array_name
Closes the db file previously associated to the array  array_name by 
a previous DBOPEN command.

see also : DBOPEN

 
 DBOPEN 
 
 

DBOPEN file_name array_name 
associates the array array_name  with the db file file_name. Each 
operation on the array will be propagated to the file : access, 
change, delete, exist(), nextlm() etc... Any db file can be 
accessed.

 DCALGO 
 
 

DCALGO n
Selects the which kind of data will be used for the first 
segmentation step of BCORR 3 when Dynamic clustering is used.
+1 : the algorithm runs on the data set.
+10 : the algorithm runs on the first derivative of the data set.
+100 : the algorithm runs on the second derivative of the data set.

 DIAG 
 
 

DIAG {direc}
In 2D, extracts the diagonal of the 2D and put into the 1D buffer
In 3D, extracts one diagonal plane of the 3D cube, chosen with the 
direc parameter
and put it into the 2D buffer

see also : COL DIM PLANE ROW VERT

 
 DIAGONALIZE 
 
 

Diagonalize the current 2D buffer (must be square and real), puts 
the eigenvalues
into the 1D buffer, sorted in decreasing order; and puts the 
eigenvector matrix
into the 2D buffer

 DIALOGBOX 
 
 

DIALOGBOX dialog_name ...
   ... [field_name field_type [field_list [enum_list] field_var 
default_value] | separator ] (n times) *
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 resume the execution of Gifa
Cancel closes the form, abort the command and generate an error
	The dialog is also composed en fields which appear one on each 
line in the window. A dialog can hold as many field as needed. Each 
field has :
* a name field_name that will show on the left side of the field
* a type field_type which is chosen in the following list : ( 
message, string, int, real, file, enum)
message type of field have no other field, this kind of entries 
serves to put plain text in the dialog
* All other type have a field_var entry which determines the name of 
the Gifa vairable in which the user input will be stored, and the 
default_value entry which determines the value of that variable when 
creating the form.
string int real and file types of field have no other entry. 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 
field_var.
file entries will have a small arrow which permits to open a 
standard file dialog window.
enum have an additional entry : enum_list.. This kind of field will 
appear as a pop up menu permitting to choose between the entries 
defined in the list : enum_list. This list is a single blank 
separated word, each item being separated with commas.
	The special entry separator  is not associated to a variable, but 
permits to enter a separator in the dialog.
	The list is terminated with a star.

 DIM 
 
 

DIM n  (n=1 or 2)
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.

 DISCONNECT 
 
 

Journaling is resumed to the standard gifa.log files when previously 
redirected with the CONNECT command.

 DISJOIN 
 
 

disconnect the previously connected file with the JOIN command

 disp 
 
 

 obsolete, for compatibility

 
 DISP1D 
 
 

DISP1D 0/1
When DISP1D is set to one, the window displaying the content of the 
1D buffer is opened. The window is closed if DISP1D is 0.

 DISP2D 
 
 

DISP2D 0/1
When DISP2D is set to one, the window displaying the content of the 
2D buffer is opened. The window is closed if DISP2D is 0.

 DISP3D 
 
 

DISP3D n
When DISP3D is set to 1, a graphic window is opened which will be 
used by the REF3D command to display 3D vues of the current3D data-
set. The size of the window is set to max(cx,cy,cz) in each 
dimension.

 DIST 
 
 

This command will issue the distance value as computed from the 
reference
distance, set by CALIBDI, and the current relaxation rate, set by 
RELAXRATE

 DSA 
 
 

DSA shift factor.
Adds to the current data set the same data set multiplied by factor 
and shifted left by shift points. Useful for suppression of water 
signal at zero frequency.
 

 
 DT->AR 
 
 

Calculates the autoregressive coefficients directly from the data 
using the Burg method. 

see also : AR->DT ARLIST BURG ORDER

 
 DT->SVD 
 
 

DT->SVD size
Calculates the Toeplitz rectangular matrix from the data and perform 
the singular value decomposition. size is the size of data used in 
the formation of Toeplitz matrix. This is the first step of the LP-
SVD spectral analysis method. The same singular value decomposition 
can be used to perform forward and backward analysis.

 DUMP 
 
 

Lists the values of all the variables presently defined within GIFA.
Each value is shown with its associated context : context 20 is the 
global context, higher context are associated to higher call levels.
