This package consists of two MATLAB functions to assist users with
choosing the thresholds for wavelet denoising using the Cromwell
package.

[1]
function [smoothed, thresholds] = sizerPrep(inten, thresholds, infinity)

This function takes three inputs
     inten = the raw spectrum intensities
     thresholds = a vector of threshold settings to apply (default = 4:100)
     infinity = a really large threshold setting (default = 1000)
The output consists of two objects
    smoothed is a matrix containing the smooth spectra for all thresholds
    thresholds is the vector of thresholds
The outputs can be used as inputs to the corresponding plotting routine,
sizerPlot.

[2]
function sizerPlot(spec, smoothed, thresholds, sml, range)

The inputs of this function are
    spec = the raw intensity spectrum
    smoothed = a matrix of smoothed spectra from sizerPrep
    thresholds = a vector of thresholds from sizerPrep
    sml = a vector of thresholds that should be displayed
    range = a vector of spectrum time points to display

The function returns no outputs. Instead, it produces a graph containing a
heatmap of the deviations of the smooth spectra from the "infinitely
smoothed" spectrum, along with overlays of the raw spectrum and the smooths
corresponding to the minimal and maximal displayed thresholds.
