select from:

• plain FT (best for integrations)
• WFT (apply default window/weighting/apodization function)
• two levels of resolution enhancement
• two levels of sensitivity enhancement
• adjust window functions interactively

• Use the Phase button and click on Done when finished. Use other buttons as needed.
• Parameters rp and lp should be reasonable:

360 > rp,lp > -360

• Reset to zero if needed and start again

• Put cursor on any desired peak and assign a reference chemical shift or use default referencing

• start with full or partial
• adjust Level and Tilt of integral if needed, finish with Done button
• set Integral Resets with left clicks (right click: undo last set point)
• clear all resets if needed
• put cursor on desired integral region and set integral reference
• Baseline correction: all peaks including solvent and major impurities MUST be integrated.

• adjust Threshold for peak pick, finish with Done button
• display peaks in Hz or ppm
• plotting has its own selection of Hz vs. ppm

• Grab and Move: move the spectrum with the left mouse button, must be finished with Done
• vertical scale adjusts so largest peak fits; can be undone
• up to 9 individual views can be saved and retrieved

Text can be added, modified, deleted directly in the text box shown below:

• parameters can be displayed in a separate window (equivalent to the dg, dg2, dg1, dglp, da, and dgs commands)
• Save/Reload for previously saved data only, NOT FOR INITIAL SAVING OF DATA (see 7.1)
• the current filename can be shown
• Spin Simulation can be entered here which leads to a new window

• Select from a variety of the plotting styles. All include a scale in ppm and text.

• WFT2D: process spectrum in both dimensions (F2 and F1)
• Adj F1 Win & WFT2D: use if experiment is still running; F1 window function will be adjusted dynamically
• WFT 1st incr: use for some phase sensitive expts. (i.e TROESY), process and then phase 1st increment

• For phase-sensitive expt’s such as TROESY and GHSQC.
• Phase 1st increment
• Phase both F1 and F2 dimensions of 2D map
• Parameters rp, lp, rp1, and lp1 should be reasonable:

-360 > rp,lp > 360

-360 > rp1,lp1 > 360

• Click on Done when finished and use other buttons as needed.

• Put cursor on desired peak and assign reference chemical shift (F2 and F1) or use Default referencing

• Increase and decrease vertical scale by step size indicated.

• select display with or without grid
• default axis (F2) normally does not need changing; F2 and F1 radio buttons  result in 90o rotation of spectrum
• contours can be displayed:
• positive and negative (+ and -)
• positive only  (+ only +)
• negative only (- only -)
• Trace @ Cursor: 1D trace at the top of the 2D
• Trace as 1D: selected trace as 1D without the 2D
• up to 9 individual views can be saved and retrieved

Text can be added, modified, deleted directly in the text box shown below:

• parameters can be displayed in a separate window (equivalent to the dg, dg2, dg1, dglp, da, and dgs commands)
• Save/Reload for previously saved data only, NOT FOR INITIAL SAVING OF DATA (see section 7.1)
• the current filename can be shown

• Select from any of the plotting styles as desired. All include scales in ppm and text.
