Sparky NMR Analysis Quick Guide
Finding and Loading Spectra:
- Navigate to your NMR data directory and execute
find . -name 2rrto locate all 2D spectrum files (TOCSY, ROESY, NOESY). - Load the identified files into Sparky for analysis.
Viewing Options and Pointer Modes:
- Access spectrum viewing options by
vtshortcut or throughView -> View options. Alternatively, right-click inside a spectrum window. - Default pointer mode can be initiated via
View -> Pointer Modesor withF1-F12keys.
Peak Selection and Manipulation:
- Select peaks using
F8. - Adjust contour levels with the
ctshortcut to modify signal visibility. - Move or delete peaks by switching to “select” mode, using the mouse to drag or select, and pressing the delete key to remove peaks.
- Undo peak deletions with
eu.
Peak Labeling and Copying:
- To label a peak, type
atand fill in the details in the prompt for residue and atom assignment. - Copy peaks with assignments using
oc(ornament copy), then paste usingopin another spectrum window.
Spectrum Overlay and Printing:
- Overlay spectra using
olafter ensuring axes are named identically. - Print contour plots to a PostScript printer with
pt; save outputs directly if supported.
Peak Assignment Commands:
- Assign or select peaks using specific commands like
pafor all peaks,pFfor fully assigned, orpLfor long range assignments. - Change peak color selection with
pCand invert selections withpI.
Miscellaneous Commands:
- Display axis atom names with
xa. - Duplicate spectrum views for comparison with
vd. - Adjust label font sizes in contour plots using
oz. - For precise plotting dimensions, refer to Plotting spectra with Sparky.
View Management:
- Hide or reveal views using
vhto hide, or select by name from the View menu to reveal. - Manage crowded screen space by iconifying or maximizing views as needed.
