Art Palmer's 1991 JACS paper

Do this for PEAK HIGHTS determination.

The empty region RMSD is smaller than the random coil region, due to power conservation in the Fourier transform. <br>
You can see this by dropping all the way to the baseplane and carefully looking. <br>
You should measure with boxes near the peaks, and make sure no peaks are in the box. <br>
This estimate is much better than the full spectrum RMSD measures from the other programs.

== Software to use ==
SPARKY. In the extension menu.

In F1 mode, draw boxes in the empty regions for all spectra. You have a different error estimate for each spectrum, which relax handles.

== Notes ==
The error is equal to the baseplane RMSD times the number of 2D spectra points in the box.<br>

== Peak shifts ==
Be aware of peak shifts, due to temperature
