MetaGPipe is a wrapper of the QIIME framework and FungalITSExtractor tool . It was especially designed to analyze PCR amplicons of fungal ITS regions sequenced with 454 technology. It was then successfully used with Illumina MiSeq reads.
MetaGPipe extracts ITS regions from input sequences and clusterizes them with uclust by using 97% similarity as a cutoff. Each cluster is designated by its most representative sequence. Taxonomic assignation is then performed by Blast against a filtered databank of ITS regions.
A reclustering step could be launched to study intra-cluster variability and highlight sequencing errors. In this case, we recommend to set the threshold to 1 (100% of similarity).
MetaGPipe workflow
Context
MetaGPipe was developped in the frame of the FungiGrapeMetaG project . MetaGPipe results were presented during the 27th fungal genetics conference ( poster ).
Availability
MetaGPipe is available to download ( MetaGPipe source code ). The documentation describes how to install and run the pipeline. MetaGPipe requires several dependencies (programs and python modules). To avoid laborious install party, we provide a virtual machine "ready to run" on Virtualbox.
