IPC (Isotopic Pattern Calculator) is a tool for mass spectrometry that calculates the isotopic distribution of a given chemical formula or peptide sequence. It uses gnuplot to visualize the results.

GIPS uses now a complete list of elements and
isotopes. The list of elements is taken from the
NIST. A "new" menu entry was added to reset the
results. The display of sum formulas was rebuilt,
and now it utilizes pango to display subscripts.
