AMPHORA ("AutoMated Phylogenomic infeRence Application") is an open-source bioinformatics workflow.

Most of the marker genes are single copy genes, therefore AMPHORA2 is suitable for inferring the accurate taxonomic composition of bacterial and archaeal communities from metagenomic shotgun sequencing data.

First AMPHORA was used for re-analysis of the Sargasso Sea metagenomic data [3] in 2008, but recently there are more and more metagenomic datasets in the Sequence Read Archive waiting for analysis with AMPHORA2.

AmphoraNet [4] is the web server implementation of the AMPHORA2 workflow developed by the PIT Bioinformatics Group.

AmphoraVizu [5] is a web server developed by the PIT Bioinformatics Group which is capable to visualize outputs generated by the AMPHORA2 or its webserver implementation AmphoraNet.
