Visual Tree Comparer

A simple graphical tree comparison tool that visualizes differences between up to four different trees by highlighting the branches (bipartitions/splits) that are not shared among those trees.

Tree Visualization Tool (very old)

Old Tree visualization tool using treemaps and taxonomic information.

AxParafit

Phylogenetic Binning tool

The code from the paper: S. Berger, R. L├╝cking, A. Stamatakis on “Morphology-based phylogenetic binning of the lichen genera Graphis and Allographa (Ascomycota: Graphidaceae) using molecular site weight calibration”.

ForeSeqs

Prediction of missing sequences and branch lengths on phylogenies inferred using MSAs that have missing/gappy data.

PTP

A tool for delimiting species on phylogenies and evolutionary placements.

MPTP

A substantially faster, more scalable, and more accurate version of our PTP tool for single locus species delimitation

PEAR – Paired-End reAd mergeR

An ultrafast, memory-efficient and highly accurate pair-end read merger. It is fully parallelized and can run with as low as just a few kilobytes of memory.

PEAR evaluates all possible paired-end read overlaps and without requiring the target fragment size as input. In addition, it implements a statistical test for minimizing false-positive results. Together with a highly optimized implementation, it can merge millions of paired end reads within a couple of minutes on a standard desktop computer.

Downloads

The PEAR creative commons license prohibits commercial use of the code. For testing and using PEAR on a commercial basis you need to purchase a commercial software license.

If you are a member of an academic institution and you use this software solely for research purposes, you can download this.

GapMis

A tool for flexible pairwise sequence alignment with a variable, but bounded, number of gaps.

libgapmis

An ultrafast library for pairwise short-read alignment, based on GapMis, including accelerated SSE-based and GPU-based versions.

genesis

A toolkit for working with phylogenetic data, mainly for evolutionary placements of short NGS reads on a reference phylogenetic tree. The library supports data in jplace format and their visualization. It also offers some basic methods to work with trees and sequences.

Evolutionary Placement Algorithm

Algorithm for placing short reads onto a given reference phylogeny. This is part of standard RAxML.

PaPaRa

PArsimony-based Phylogeny-Aware Read alignment program. The tool uses a given multipe sequence alignment and corresponding reference tree to align short reads for analysis with the EPA (Evolutionary Placement Algorithm).

MoTeX

An accurate and efficient tool for MoTif eXtraction.

ChromatoGate

A tool for analyzing and editing/correcting chromatogram data.

SATIVA

Semi-Automatic Taxonomy Improvement and Validation Algorithm. Identifies taxonomically mislabeled sequences and suggests corrections using EPA (Evolutionary Placement Algorithm).

EPA next generation

Stand-alone, much faster, and massively parallel re-implementation of the Evolutionary Placement Algorithm.

AnA-FiTS

A very fast forward-in-time simulator for population genetics.

Sweed

A parallel and checkpointable tool that implements a composite likelihood ratio test for detecting selective sweeps. SweeD is based on the SweepFinder algorithm.

OmegaPlus

A parallel tool for rapid & scalable detection of selective sweeps in whole-genome datasets using the omega statistic.
