First, try phasing without optimizing phase 1 for a fast preprocessing. In many cases, this produces a very acceptable result for fingerprinting approach.

If the resulting phasing is not acceptable, then try phasing with optimizing phase 1.

In the advanced settings, you can also test KZEROTHRES=5, 100, or 500 successively to see if this improves the phasing.

Remember to use the'reset' button to avoid reloading the ZIP file.

In order to calibrate the ppm scale when a set of spectra has not been acquired with the same locking frequency, it is possible to ignore the spectral region center parameter due to the fact it exhibes in this case large differences between spectra.

Instead, the zero will be located at the third of the sweep width.
