Description: sRNA-TaBac is a web visualization interface for target predictions. It allows you to load our data and visualize them througt a friendly interface. It is a tool to help you to explore all your data from one or several software. Key features: i) load easily our data: input format GFF3 like (see Data Format), ii) give our reference genome, iii) fold our actors and see interaction on it, iv) convert data into alignment-like format (see Alignment-like Format), v) save our table result into CSV, vi) implementation of several filters.

Availability: sRNA-TaBac is not yet available.



Description: In sRNAseq data sets, only a very small fraction of reads can be assigned to a known functionnal family resulting in a lot of sRNAseq data orphan of functional annotation. The bias introduced by errors, the editing of some sequences but also the lack of similarities in existing ncRNA databases make challenging their structural and functional annotation. sRNAseq data analysis tools such as miRDeep,  miRanalyzer and others focus on microRNAs annotation and prediction, neglecting other types of RNAs. Recently, web tools such as DARIO, Ncpro enlarged functional annotation. sRNAbrowse is a software under development which aims at profiling, annotating and exploring as many sRNAseq data as possible, considering different ncRNA families and differential expression in multiple conditions and/or tissues.

Availability: sRNAbrowse is freely available on the mulcyber forge.

Description: Building rich WEB environments aimed at helping scientists analyse their data is a common trend in bioinformatics. These applications are often specialized WEB portals or generic Workflow management systems (WMS). The first class provides multiple services and analysis tools in an integrated interface for a specific experiment or data type. Quite often these systems hide the processing steps in the back-office. The second class is mainly focused on workflow creation and provides a rather poor end-user interface but enable to combine tools and data sources as desired. Jflow is a fully scalable WMS that can easily be embedded in any WEB site, providing all WMS features and benefits to your project.

Availability: Jflow code is freely available on the mulcyber forge.

Description: jvenn is a plug-in for the jQuery Javascript library. It is a flexible tool, based upon the venny tool first developed by J.C Oliveros (Oliveros, J.C (2007) VENNY, An integrative tool for comparing lists with Venn Diagrams). Key features: hanldes up to 6 classes venn diagram, allows to display Edwards-Venn diagram, is easily integrable within your own web site, allows to provide the data from 3 different ways (lists/intersection counts/count lists), control the click callback function, provides statistic charts based on input data, search for elements, exports the venn diagram to PNG and SVG, exports lists to CSV.

Availability: The plugin code and its documentation is freely available on the mulcyber forge. A running version of the plugin is also available from our WEB site.

Description : Transcriptome analysis based on a de novo assembly of next generation RNA sequences is now performed routinely in many laboratories. The generated results, including contig sequences, quantification figures, functional annotations and variation discovery outputs are usually bulky and quiet diverse. RNAbrowse is an user oriented storage and visualisation environment permitting to explore the data in a top-down manner, going from general graphical views to all possible details. The software package is based on biomart, easy to install and populate with local data.

Availability: The software package is available under the GNU General Public License (GPL) and can be downloaded from the mulcyber forge.

Description: The platform works in tight collaboration with the GeT sequencing platform for the management and the analysis of data produced by their Roche 454 and Illumina HiSeq sequencers.
NG6 is an extensible sequencing provider oriented LIMS. It includes read quality control and first level analysis processes which ease the data validation made jointly by the sequencing facility staff ant the end-users. It provides a secured user-friendly interface to visualize and download the raw sequences files and the analysis results.

Availability: The NG6 code is freely available on the mulcyber forge. To ease the installation, the package and all its dependencies are also available as a virtual machine. Installing and maintaining the system would require expertise in Linux system administration.

Description: The pyrocleaner is intended to clean the reads included in the sff file in order to ease the assembly process. It enables filtering sequences on different criteria such as length, complexity, number of undetermined bases which has been proven to correlate with poor quality and multiple copy reads. It also enables to clean paired-ends sff files and generates on one side a sff with the validated paired-ends and on the other the sequences which can be used as shotgun reads.

Availability: The PyroCleaner code is freely available on the mulcyber forge.

Description: RNAspace is a platform which aims at providing an integrated environment for non-coding RNA annotation.
The increasing number of ncRNA discovered since 2000 and the lack of user friendly tools for finding and annotating them, have made necessary to propose to biologists an in silico environment allowing structural and functional annotations of these molecules with regard to available protein genes annotation environments.
RNAspace makes available a variety of ncRNA gene finders and ncRNA databases as well as user-friendly tools to explore computed results including comparison, visualization and edition of putative RNAs. RNAspace also allows to export putative RNAs in various formats.

Availability: RNAspace is an open source project. It is developed in Python. It is copyrighted with the GNU General Public License, and is free (in the GNU sense) for all to use, and is in constant development. RNAspace is hosted at Sourceforge. It is also available as a web server at rnaspace.org.
