(BETA VERSION)
This code implements the type-oriented algorithm (TOA) for baseline correction developed by Christopher J. Wong at the University of Utah. The TOA is the most powerful and flexible tool for baseline correction available. The theory behind, and application of, this method is described by Wong [1] and it is loosely based on the approach described by Pan et al. [2].
This File Exchange package is still under heavy development, but it is fully tested and produces high quality results. There are various demonstrations included that follow a basic syntax format and can be used as a guide for setting up new scripts, but more documentation and complete instructions will become available in the near future. Please contact the author if you have any questions.
