gad

setup for gull & Daniell MAXENT iteration
see also : conjg gifa MAXENT


GAMA

gama g This context is the angle along the OX axis by which the cube is rotated during a 3D display with the DISP3D/REF3D set of commands
see also : ALPHA BETA DISP3D


gaussbroad

gaussbroad lb { axis } this macro applies a exponential broadening in nD it actually duplicates the GM functionnality, but but, uses the same syntax as SIN and SQSIN contexts : $GB1 $GB2 $GB3
see also : expbroad GM SIN


GB

Constant used for Gaussian deconvolution during MaxEnt. Set also by the GM command related contexts : $GB1 $GB2 $GB3
see also : EM FILTER GM LB


GET

GET buffer_name Moves the content of another buffer, back to the current buffer with buffer_name equal to: DATA: get the content of the Data buffer LINEFIT: get the simulated spectrum obtained form the current peak table WINDOW: get actual window used to compute the chisquare FILTER: get filter used for Deconvolution LAMB: get evolution of Lambda during MaxEnt iteration ENT: get evolution of Entropy during MaxEnt iteration CHI: get evolution of ChiSquare during MaxEnt iteration SUM: get evolution of Sum of point of Image during MaxEnt iteration CONV: get evolution of Convergence during MaxEnt iteration STEP: get evolution of Step during MaxEnt iteration RESIDUE: get residue of the spectrum after a MaxEnt run AMOEBA: get the Amoeba map used during the last integration (in 2D only) TAB get the Tab buffer used for tabulated fit related contexts : $SI_TAB $TAB[] $ITERDONE
see also : APPLY PUT SHOW


GETC

Get data from the currently joined data-set. syntaxe depends on the dimentionnality of the currently joined data- set (from) and on the current context dim (to) : 1D to 1D : GETC left right 2D to 1D : GETC axis index left right 3D to 1D : GETC axis index1 index2 left right 2D to 2D : GETC left1 left2 right1 right2 3D to 2D : GETC axis index left1 left2 right1 right2 3D to 3D : GETC left1 left2 left3 right1 right2 right3 Loads from the currently connected file, the area of data as described. related contexts : $C_JOINED
see also : dataset JOIN LISTFILEC PUTC


GETHEADER

GETHEADER param_name value Display the value of a parameter associated to the currently JOINed data-set. Any parameters can be used. Gifa already uses the following parameters (as listed with the dataset command) : Frequency, Freq1, Freq2, Freq3, Specw1, Specw2, Specw3, Offset1, Offset2, Offset3, Type, Dim. But parameters created with PUTHEADER can also be used. The value of the last read parameter is set into the Gifa $c_header variable. related contexts : $C_JOINED $C_HEADER
see also : dataset JOIN NEWFILEC PUTHEADER


getuxnmr

This macro is a wrapper around the getnmr / getexp utilities, permitting to bring UXNMR data-sets from a BRUKER spectrometer to the computer, and to convert them to Gifa format. It is to be used if you want to copy the data files from the spectrometer to the workstation through the network (actually getnmr / getexp does this) In the case you simply want to convert from UXNMR files to Gifa files on the local disk, use the ux2cach.sh shell script instead.

gifa

set up for GIFA MAXENT algorithm
see also : conjg gad MAXENT


GIFAPLOT

gifaplot file_name plotter-type in /usr/local/gifa/com This is a shell script which is called by the PAGE command, whenenver a plot is to be issued to the currently defined plotter. This shell script should adapted to your current set-up.

GM

GM gb1 { gb2 { gb3 } } Multiply data by an Gaussian, and set GB. related contexts : $GB1 $GB2 $GB3
see also : EM FILTER gaussbroad GB JMULT LB SIN SQSIN TM


gm_bruker

gm_bruker lb gb will perform a Gaussian apodisation in the Bruker manner lb is negative, gb goes from 0 to 1 will set LB and GB (gifa ones) to their corresponding value)
see also : EM GM sin_bruker


gm_inter

interactive Permits to explore the effect of a gaussian apodisation start with a FID in memory, and with the correct phase correction in memory GB is the size in Hz of the feature you want to select -LB/GB rration selects the strength of the enhancement Click on Apply to see the effect. try DO_NOTHING as ft if you want to see the effect on the FID To start with a new data set, read it in and click on 'New FID'
see also : EM GM


go

obsolete, for compatibility

GOTO

GOTO label Will branch the flow a macro to the label. Labels are alphanumeric strings, and appear preceded by an = sign in macro text. Labels should be alone on the line. GOTO cannot be used in interactive mode, but only in macros.

GRID

GRID direc plot_file This command draws a set of horizontal (if direc=F2 or F12) and vertical (if direc=F1 or F12) lines. A CX by CY space is spanned. The grid lines are plotted as defined by the plotaxis? command,. The plot is sent to plot_file.
