PeakData

PeakData is a table of TraceBase output analagous to an accucor input file labeled with sample information. It contains sample metadata and two basic values:

• Corrected Abundance - the abundance of each observed isotopomer for each compound (corrected for natural isotope abundance). (ion counts)
• Fraction - the simple fraction of this isotopomer vs all others for this observed compound.

Downloaded PeakData has a standard format.

PeakData is used to construct PeakGroups.
