Where are my files?Working “data” directory – Open (GA) and Save (SA) commands“Import” directory – where NUTS looks for foreign files (IM)
These paths are defined in nuts.ini, but change dynamically as files are opened or saved
WP (Which Path) command – where am I?
Import data with IM command
Save processed data with SA command
What is saved in my file?Data is saved as you see it on the screenIntegrals, Peak list, etc, saved in file “tailer”
Auto Tailer Read option under the File menu – controls whether or not integrals, etc, are read when a file is opened; can be set in nuts.ini file

Baseline correct the FID – BCto prevent “center glitch”
DC offset between real and imaginary FIDs
Offset creates glitch BC removes glitch

Phasing with NUTSStart with QP – quick automatic phasingTouch up phasing with one of the manual, mouse-driven phase routines
![Page 23: NUTS NMR Utility Transform Software Acorn NMR, Inc. Livermore, CA.](https://reader033.fdocuments.in/reader033/viewer/2022061304/5513d12355034646298b511e/html5/thumbnails/23.jpg)
Manual phasing with mouse Left and right mouse buttons apply zero-order and 1st- order correction
PH – Do this on full spectrumSet pivot point – place cursor and type P
Zero-order correction with left buttonAdjust peak at pivot point
First-order correction with right button to phase the rest of the spectrum
Exit subroutine with <ENTER> key
![Page 24: NUTS NMR Utility Transform Software Acorn NMR, Inc. Livermore, CA.](https://reader033.fdocuments.in/reader033/viewer/2022061304/5513d12355034646298b511e/html5/thumbnails/24.jpg)
PE – Phase Expanded, for more close-up viewdefine 2 regions, phase each using expanded displaySwitch between regions with 2 mouse buttons
To define the 2 regions, use Zoom:
select 1st region, type 1 select 2nd region and type 2
Exit Zoom and enter PE routine
![Page 25: NUTS NMR Utility Transform Software Acorn NMR, Inc. Livermore, CA.](https://reader033.fdocuments.in/reader033/viewer/2022061304/5513d12355034646298b511e/html5/thumbnails/25.jpg)

Baseline correction of the spectrum
Distortion can be combination of DC offset – removed by BCLinear tilt – removed by BCHigher order roll – polynomial
Best method of correction is dependent on characteristics of each spectrum
![Page 28: NUTS NMR Utility Transform Software Acorn NMR, Inc. Livermore, CA.](https://reader033.fdocuments.in/reader033/viewer/2022061304/5513d12355034646298b511e/html5/thumbnails/28.jpg)
Poor baseline may be most apparent when viewing the integral – if it isn’t flat, the baseline isn’t at zero.
![Page 29: NUTS NMR Utility Transform Software Acorn NMR, Inc. Livermore, CA.](https://reader033.fdocuments.in/reader033/viewer/2022061304/5513d12355034646298b511e/html5/thumbnails/29.jpg)
QB (Quick polynomial Baseline correction) works in most cases, especially if peaks are sharp and signal-to-noise is good.
More baseline correction features are available; see Help

Automatic Integration – AI
Integrates all peaks above Minimum Height (MH) threshold
Sets smallest integral to 1.0
If full spectrum is displayed, AI clears previous integrals before integrating
If expanded region is displayed, AI appends integrals to a growing list, allowing successive selected regions to be integrated to create a complete integral list. Scaling is not re-set for successive regions.
Works best for spectrum with well-resolved peaks and no impurities
![Page 32: NUTS NMR Utility Transform Software Acorn NMR, Inc. Livermore, CA.](https://reader033.fdocuments.in/reader033/viewer/2022061304/5513d12355034646298b511e/html5/thumbnails/32.jpg)

Manual integration
ID subroutine, exit with <ENTER>
Scaling the integral vs. scaling the spectrum
Correct the baseline, not the integral!
Define start and stop points for each sub-integral by left mouse clicks
Assign a convenient value to one of the sub-integrals with V key
The scaling factor remains until explicitly changed, regardless of scaling.

Putting structures on screen - MetaObjects (MO) subroutine
Paste structure from clipboard or import Windows Metafile (.wmf)
If imported from a file, a “pointer” to that file will be saved when the data file is saved, so can be recalled later
Can create, move, re-size multiple objects
Can also be used to create inset plots, but Inset Plot routine (IS) usually gives better results

Automation
Command “links” – frequently used string of commands LI – display link definitions (set by nuts.ini)A# (where # = 1, 2, …) executes the corresponding Link
Example for routine processingbc em ft qp
Macros – text files containing NUTS commandsMore flexible and powerful than Links
