Perform Non-Negative Matrix factorization on list of SPC files

Description

Perform Non-Negative Matrix factorization on list of SPC files

Usage

initSpectralData

list of SPC files containing pure component spectra

nruns

number of NMF runs.

subsamplingFactor

subsampling factor used during NMF analysis

checkDivergence

Boolean indicating whether divergence checking should be performed
