Setup Arrayed Spectra |
This feature for the vertical & horizontal alignment of stacked spectra is available after having clicked on the 'Adjust Stacked Items' button:
The way in which this control works is explained directly in the panel, in the same manner as with the phase correction panel:
Horizontal shifting: To align the spectra just click&grag to right or left. When the spectrum is shifted to the left or to the right, its chemical shift reference is adjusted to reflect that horizontal move. Vertical scaling: This consists in changing the internal data points in the spectrum array by multiplying each point by a scaling factor. Note that this will have implications in the quantitation results. Reset Intensities: this button will restore the intensity changes Reset Shifts: this button will restore the shift changes.
Clicking on the pin scroll down menu will allow you change the selection of your spectra:
Every change carried out during this process will be reflected in the stacked table. For example, if you move one spectrum 15 Hz to the right, that result will be shown in that table, so that it will be possible to use that value to measure, for example, a coupling constant or the amount by which a spectrum was shifted so that it perfectly overlaps with another spectrum.
