Serves for integration of metabolomic data from multiple batches, visualization and statistical analysis for non-targeted and targeted approaches of quantitative mass spectrometry-based omics data. StatTarget is based on the QC-RFSC algorithm to remove inter- and intra-unwanted variation. This tool aims to improve data quality of quantitative mass spectrometry-based omics data. It can be extended to perform on other biological data such as protein or peptide expression data.
Normalizes the uploaded data using twelve different well known normalization methods and compares the resulting data based on quantitative and qualitative parameters. Normalyzer is completely automated online tool for data normalization. There are no parameters to configure and no scripts to install.
Recalibrates the mass-to-charge ratio error of most observed parent ions to the sub part per million level in routine experiments. First, many new parameters were introduced and screened as features online to reduce systematic error and to adapt to various data sets. Second, a support vector regression model was trained to characterize the complex nonlinear maps from features to mass-to-charge ratio measurement errors. Third, a specific mass-to-charge ratio error tolerance for each parent ion was estimated by considering the impact of signal intensity. FTDR 2.0 is a user-friendly tool that supports most commonly used data standards and formats. A C++ library and the source code are provided to support the redevelopment and integration into other mass spectrometry data processing tools.
Gives a visual evaluation of the well-calibration of the p-values. Cp4p can deal with a vector of previously computed p-values. It enables researchers to determine the proportion of non-differentially abundant (DA) proteins in relative quantification experiments. This tool promotes false discovery rate (FDR) control procedures of the BH family. It can process any quantitative datasets, regardless of the experimental design.
