Software developed within the Freiburg Galaxy Project

A variety of different tools that can be installed and used inside the Galaxy. Many tools are already included in the Galaxy Tool Shed. Galaxy logo
The Galaxy Docker Image is an easy distributable full-fledged Galaxy installation, that can be used for testing, teaching and presenting new tools and features. Docker logo
The RNA workbench is Galaxy Docker instance specifically set up for high throughput RNA analyses. It is developed by the RNA Bioinformatics Center, which is part of the German Network for Bioinformatics Infrastructure (de.NBI). Bioinf Freiburg logo
This projects integrates IPython Notebook, a interactive computational environment, with Galaxy. We hope to make Galaxy more attractive for bioinformaticians and to combine the power of both projects to unlock creativity in data analysis, but also in Next-Generation-Training courses. Check this Galaxy IPython Video to get an idea of its potential. IPython logo

EDeN - Explicit Decomposition with Neighborhoods

The Explicit Decomposition with Neighborhoods (EDeN) is a decompositional kernel based on the Neighborhood Subgraph Pairwise Distance Kernel (NSPDK) that can be used to induce an explicit feature representation for graphs. This in turn allows the adoption of machine learning algorithm to perform supervised and unsupervised learning task in a scalable way (e.g. fast stochastic gradient descent methods in classification).
Among the novelties introduced in EDeN is the ability to take in input real vector labels and to process weighted graphs.
BlockClust

BlockClust is an efficient approach to detect transcripts with similar processing patterns. We propose a novel way to encode expression profiles in compact discrete structures, which can then be processed using fast graph-kernel techniques. BlockClust allows both clustering and classification of small non-coding RNAs.

BlockClust runs in three operating modes:
  1. Pre-processing - converts given mapped reads (BAM) into BED file of tags
  2. Clustering and classification - of given input blockgroups (output of blockbuster tool) as explained in the original paper.
  3. Post-processing - plots for overview of predicted clusters.

For a thorough analysis of your data, we suggest you to use complete blockclust workflow, which contains all three modes of operation.

BlockClust Galaxy tool is available in the Galaxy toolshed. BlockClust complete Galaxy workflow with all three operating modes is also available in the toolshed.

IntaRNA - efficient RNA-RNA interaction prediction incorporating accessibility and seeding of interaction sites

During the last few years, several new small regulatory RNAs (sRNAs) have been discovered in bacteria. Most of them act as post-transcriptional regulators by base pairing to a target mRNA, causing translational repression or activation, or mRNA degradation. Numerous sRNAs have already been identified, but the number of experimentally verified targets is considerably lower. Consequently, computational target prediction is in great demand. Many existing target prediction programs neglect the accessibility of target sites and the existence of a seed, while other approaches are either specialized to certain types of RNAs or too slow for genome-wide searches.

IntaRNA, developed by Prof. Backofen's bioinformatics group at Freiburg University, is a general and fast approach to the prediction of RNA-RNA interactions incorporating both the accessibility of interacting sites as well as the existence of a user-definable seed interaction. We successfully applied IntaRNA to the prediction of bacterial sRNA targets and determined the exact locations of the interactions with a higher accuracy than competing programs.

For ad hoc usage, refer to IntaRNA @Freiburg RNA tools.

IntaRNA can be most easily installed locally via badge using

conda install intarna

See Bioconda for further details.

You can download the IntaRNA source code packages (as well as precompiled binaries) from IntaRNA-releases @github.

LocARNA - Global and Local Alignment of RNA.
A tool for pairwise and multiple, global and local alignment of RNA with simultaneous folding. LocARNA requires only RNA sequences as input and will simultaneously fold and align the input sequences. Specifications of additional constraints or fixed input structures are possible. For the folding it makes use of a very realistic energy model for RNAs as it is by RNAfold of the Vienna RNA package (or Zuker's mfold). For the alignment it features RIBOSUM-like similarity scoring and realistic gap cost.
CARNA - alignment of RNA structure ensembles.
CARNA is a tool for multiple alignment of RNA molecules. CARNA requires only the RNA sequences as input and will compute base pair probability matrices and align the sequences based on their full ensembles of structures. Alternatively, you can also provide base pair probability matrices (dot plots in .ps format) or fixed structures (as annotation in the FASTA alignment) for your sequences. If you provide fixed structures, only those structures and not the entire ensemble of possible structures is aligned. In contrast to LocARNA, CARNA does not pick the most likely consensus structure, but computes the alignment that fits best to all likely structures simultaneously. Hence, CARNA is particularly useful when aligning RNAs like riboswitches, which have more than one stable structure. Also, CARNA is not limited to nested structures, but is able to align arbitrary pseudoknots.
