Proteomics

QCQuan

QCQuan analyzes your labeled LC-MS/MS proteomics differential expression experiment and provides you with (normalized) output files on both the non-redundant-peptide level as well as protein level, including a quality control and differential expression report in PDF format.

Keywords: proteomics workflow; mass spectrometry; differential expression; quality control; normalization

MIND

Methods that predict the monoisotopic mass based on the average mass are potentially affected by imprecisions associated with the average mass. To address this issue, we have developed a framework based on simple, linear models that allows prediction of the monoisotopic mass based on the exact mass of the most-abundant (aggregated) isotope peak, which is a robust measure of mass, insensitive to the aforementioned natural and technical causes

BRAIN

BRAIN = Baffling Recursive Algorithm for Isotope distributioN calculations. This package calculates aggregated isotopic distribution and exact center-masses for chemical substances (in this version composed of C, H, N, O and S). This is an implementation of the BRAIN algorithm described in the paper by J. Claesen, P. Dittwald, T. Burzykowski and D. Valkenborg.

Clinical trial statistics

Surrogate

The R package 'Surrogate' allows for an evaluation of the appropriateness of a candidate surrogate endpoint based on the meta-analytic, information-theoretic, and causal-inference frameworks.

Keywords: clinical trials; endpoints
