What's new in SHAMAN

April 17th 2018 - Bioinformatics

The bioinformatic treatment offers a larger access to parameters. We also worked a lot on the documentation.


September 4th 2017 - Bioinformatics

The bioinformatic treatment of fastq reads is now available in SHAMAN. For now, SHAMAN allows to compute OTU, build an OTU table and annotate them with the last version of the available database. This application is for 16S/18S/23S/28S/ITS sequencing.


July 18th 2017 - Normalization and visualisation

A new method for normalization called total counts was added. More options have been added to the abundance tree.


May 30th 2017 - Bug fixes

Some visualization bug with the abundance tree and phylogenetic tree are now fixed. The export of the relative abundance and normalised abundance are now given in the right level. This update prepares the field for the next major release of shaman for June.


March 30th 2017 - Krona, Phylogeny and bug fixes

Krona and phylogenetic tree plots are now available in visualisation. Several new distance are available in PCOA. The import float count matrices is now ok. We have finaly debugged the export of the relative abundance/normalized matrices.


Dec 9th 2016 - Phylogenetic tree and stress plot

You can now upload a phylogenetic tree to calculate the unifrac distance (only available at the OTU level). The stress plot has been added to evaluate the goodness of fit of the NMDS.


Nov 22th 2016 - New visualization and bug fix

We have implemented a new visualization called tree abundance. Some bugs have been fixed (thanks Carine Rey from ENS).


Oct 12th 2016 - Filtering step and bugs fix

You can now apply a filter on the features according to their abundance and the number of samples. Bugs on confidence intervals for the alpha diversity have been fixed.


Sep 21th 2016 - SHAMAN on docker

The install of SHAMAN is now available with docker. The R install is also updated and passed in release candidate state.


Sep 14th 2016 - Download and install SHAMAN

You can install SHAMAN (beta).


Sep 9th 2016 - PCA/PCOA

You can select the axes for the PCOA and PCA plots.


Aug 1st 2016 - Biom format

SHAMAN can now support all the Biom format versions.


Jun 24th 2016 - Comparisons plots

The venn diagram and the heatmap of foldchange have been added to compare the results of 2 or more contrasts.


Jun 17th 2016 - Diversity plots

Enhancement of the visualtisation of the diverties. The shanon and inv. shanon have been added.
