Command List

Command List


NUTS Alphabetical Index

Listed below are commands active in the "base level" of NUTS (as opposed to within subroutines).  Most are 2-letter commands that are executed immediately, without requiring <ENTER>.  As of 5/15/99, there is an optional command mode that allows use of longer commands, including arguments as appropriate, and requiring <ENTER> before the command is executed.  Where an equivalent longer command exists, it is listed together with the corresponding 2-letter command.  See detailed explanation of this "non-2-letter command" mode.

/2 (or brickwall) — Reduce data by factor of 2 by discarding 25% at each end

*2 — Expand data by factor of 2 by adding zeroes at each end

1D — exit 2D display mode to 1D display mode

2A — Number of points to average when applying BF and FR baseline corrections
