Using this function one can read in a spectrum into the current window (not useful while acquisition is on), or save a spectrum to disk.
Reading is useful during offline analysis to go through many spectra without having to define a large setup.
Writing is especially useful to save a
projected spectrum.
In fact
there is no other way to save a spectrum after it has been projected
from a box gate or banana gate.
Some Terminology:
We consistently use the word "projection" (also X-projection and
Y-projection) to denote the reduction of a 2d spectrum to a 1d
spectrum. Some people use the same word "projection" to describe
the process of obtaining a 1d or 2d spectrum (with or without
gates) from the list file. To avoid confusion we never use
"projection" with this meaning, instead we describe this
as "building" spectra from list files.
