View source: R/preproc_utils.R
This function handles the reading in of raw MS data (.mzML, .CDF and .mzXML). Users must provide a matrix with meta information about file such that each file has the name, file path, group class and extension type. The function will output two chromatograms into the user's working directory, a base peak intensity chromatogram (BPIC) and a total ion chromatogram (TIC). Further, this function sets the number of cores to be used for parallel processing. It first determines the number of cores within a user's computer and then sets it that number/2.
