Description
SuperHirn is a novel tool to quantitatively analyze multi dimensional LC-MS data in a label-free approach and was developed by the group of Prof. Ruedi Aebersold at the Institute of Molecular Systems Biology (ETHZ, Switzerland). The software is programmed in C++ and is compatible with Unix platforms (tested on Linux and OSX). LC-MS data are preprocessed by a MS1 feature extraction routine and the different LC-MS runs are then combined by a multi dimensional LC-MS alignment into a general repository called MasterMap. SuperHirn then offers several modules for post data analysis of the MasterMap:
- LC-MS similarity analysis: Binary similarity analysis of LC-MS runs (intensity reproducibility, feature overlap)
- Feature intensity normalization: global MS1 feature intensity normalization across LC-MS runs
- Unsupervised feature profiling: Kmeans cluster analysis of MS1 features
- Targeted peptide/protein profiling: Correlate peptide/protein profile vs. a given target profile
- MS1 feature annotation: Annotation of MS1 features in the MasterMap (inclusion list etc.)
