UNIT

UNIT value The context UNIT will tel some other commands (mostly POINT) to choose the unit used. UNIT can take the values INDEX (number of channel) HERTZ (based on SPECW and OFFSET), PPM (HERTZ divided by FREQ), SECOND (usefull only for FID), TABULATED (values are taken from the TAB buffer) or DAMPING (in damping values). All other values are invalid. related contexts : $UNIT

UNREF

When this command is issued, the command line will not refresh the current display. Typically used at the end of a command line in macr : read file unref ; read the file but does not display it This is the inverse of REF

UNSET

unset variable_name Remove the variable variable_name from the variable table. Note that no $ sign are needed.

upzoom

upzoom permits to propagate a zoom window to a higher dimension Normally, each dim buffer (i.e. 1D, 2D 3D) have a independent zoom definition. however, commands like ROW, COL, PROJ (2D->1D) PLANE, PROJ (3D->2D) VERT (3D->1D) etc... copy the zoom definition from the higher dimension to the lower one. upzoom realizes exactly the opposite. if you are in nD, upzoom will copy the current zoom definition to (n+1)D using the last commands to guess the axis.

user_apod

user_apod func($i) func($i) is entered as a string which defines the function to be applied as an apodisation function. $i will run from 1 to the size of the data_set no blank should be inserted in the definition of func($i) all context can be used $pi is predefined

user_apod_2d

user_apod_2d func($i) direc func($i) is entered as a string which defines the function to be applied $i will run from 1 to the size of the data_set no blank should inserted in the definition of func($i) all context can be used $pi is predefined direc is either F1 or F2

USWA

USWA {Fx} Take a complex data set in internal representation ( i.e. odd points real and even points imaginary), and put the real part on the left side, and the imaginary part on the right side of the data set. This is the opposite of SWA. related contexts : $ITYPE_1D $ITYPE_2D $ITYPE_3D
