MS thesis. Analyzing chemical compounds in a large GCxGC-ToF-MS data repository.

My MS thesis dealt with analyzing chemical compounds in a large data repository collected with a GCxGC-ToF-MS instrument. The main contributions are two: an algorithm that compares two mass spectra to find matches, and a method that uses properties of the data run itself to locate which compounds are worth comparing at all. The FDA targets specific analytes that may cause harm to humans.

Allison's published text ends mid-sentence here ("However to identify which"). Carried up to the last complete sentence; the ending is hers to supply.
