BioVeL Metagenomic Traits Statistical Analysis workflowsThe aim of these workflows is to provide the statistical tools to analyze the taxonomic and functional make-up of metagenomic data in a rigorous ecological framework, and to provide insights into community ecology beyond purely descriptive studies. The Microbial Metagenomic Trait Statistical Analysis workflow calculates a number of ecologically interesting traits of bacterial communities as observed by high throughput metagenomic DNA sequencing. These metagenomic traits workflows are significant, as it is very likely that environmental sequencing in natural and disturbed habitats will become a routing part of monitoring programs. This workflow can be accessed through the BioVeL Portal here. The BioMaS (Bioinformatic analysis of Metagenomic AmpliconS) workflow has been designed for the taxonomic profiling of environmental microbial communities through target-oriented metagenomic surveys. It includes all the computational processing steps from raw Next Generation Sequencing (NGS) data input and cleaning to the final taxonomic identification and representation. In its current version, BioMaS allows the analysis of both bacterial and fungal environments starting directly from the output of 454 and Illumina NGS platforms. |

The easiest way to execute the workflow is by running it on the BioVeL portal, where everything is already configured for its execution. Nonetheless, the user can load and execute the workflow locally in Taverna Workbench (v2.5) if desired. When it is run in Taverna Workbench, the workflow requires a local Rserve installation running on port 6311 with the following R packages: ape, MASS, ggplot2 and RColorBrewer. It is also possible to setup the workflow to use a remote Rserve.
