+
+**What it does**
+
+This is a tool for phylogenetic tree view (newick format) that allows multiple sequence alignments to be shown together with the trees (fasta format). It uses the tree drawing engine implemented in the ETE toolkit, and offers transparent integration with the NCBI taxonomy database. Currently, alignments can be displayed in condensed or block-based format.
+
+**Input**
+
+Input trees should be in Newick format. Optionally a fasta alignment may also be provided. Leaf names in the newick tree should match those in the fasta alignment.
+
+Tip: Use NCBI numeric taxids as leaf names (or in the format TaxID.sequenceName) to get on-the-fly translation of species names and lineages.
+
+For example::
+
+    ((6669.DappuP312785:1.24473,(((7739.JGI126010:4.02e-06,7739.JGI126021:0.168081)0.99985:0.848895, [..]
+
+where 66969 and 7739 are NCBI TaXIDs.
+
+**Output**
+
+The tool will output a tree image in SVG or PNG format.
