CV_ratio.RdCalculate the coefficient of variance (CV) for samples and QC (quality control) to assess the reliability of the experiment, as: CV = (SD - mean) * 100. CV samples and CV QC are compared, calculating the ratio between CV samples and CV QC. The threshold of the ratio has to be decided by the user in ratioCV. Only metabolites with ratio >= ratioCV are used for the analysis.
