Differences from NUTS

Differences from the original NUTS program

By default, commands in the original NUTS program are 2-letter commands that are executed immediately, not requiring a <ENTER>. This created difficulties, such as shortage of 2-letter commands that clearly suggested their meaning, and the need for command arguments. wxNUTS has a more flexible command syntax. Because commands vary in length, a <ENTER> is required to execute each command.

Phasing – wxNUTS has a PH mouse phasing subroutine very similar to that of the original NUTS. One difference is that the pivot point is set while inside the PH subroutine in wxNUTS. In the original NUTS, the pivot point must be set before entering the PH routine.

Integration – the original NUTS required one left-mouse click to display a vertical red cursor, then 2 more clicks to define each subintegral. wxNUTS does not require that first click.

To set the chemical shift reference, zoom in around the peak whose chemical shift you want to set. While still in Zoom, place the cursor on the chosen peak (without pressing the mouse button) and type P. A box is displayed allowing setting of a ppm value for that peak. Typing an H, instead of P, allows the peak frequency to be set in Hz, rather than ppm.

This can be done at the program’s Base level (not in zoom) by pressing and holding the left mouse button, placing the cursor on the chosen peak and, while still holding down the mouse button, typing P (for ppm) or H (for Hz).

At this stage of development, there are no command links, but macros have been implemented.

NUTS-Pro users – there is no “arrayed mode”, as exists in the original NUTS program. 2D data is always loaded in memory, so there is no equivalent of the “non-arrayed” mode from the original NUTS program. See explanation of 2D processing.

A word about multi-dimensional nomenclature:

A 1D spectrum contains a series of points (data points). A 2D spectrum contains a series of “slices”, which are 1D spectra. A 3D data set contains a series of “planes”, each of which is a 2D spectrum. And a 4D spectrum consists of a series of “blocks”, each of which is a 3D spectrum.
