data_indexer

This function takes as input a vector and return the
data index according to the selected time frame

Processor for selected ion flow tube mass spectrometer
(SIFT-MS) output file from breath analysis. It allows the filtering of the SIFT output file (i.e., variation
over time of the target analyte concentration) and the following
analysis for the determination of: maximum, average, and standard deviation
value of target concentration measured at each exhalation, and the
respiratory rate over the measurement. Additionally, it is possible to
align the SIFT-MS data with other on-line techniques such as
cardio pulmonary exercise test (CPET) for a comprehensive
characterization of breath samples.
