How To Install percolator on CentOS 8
Introduction
In this tutorial we learn how to install percolator on CentOS 8.
What is percolator
The first step in analyzing an mass spectrometry assay is to match the harvested spectra against a target database using database search engines such as Sequest and Mascot, a process that renders list of peptide-spectrum matches. However, it is not trivial to assess the accuracy of these identifications. Percolator uses a semi-supervised machine learning to discriminate correct from incorrect peptide-spectrum matches, and calculates accurate statistics such as q-value (FDR) and posterior error probabilities.
