48 **What it does**
49
50 Given taxonomy representation (produced by *Taxonomy manipulation->Fetch Taxonomic Ranks* tool) this utility produces a graphical representations of phylogenetic tree in PDF format.
51
52 --------
53
54 **Example 1: Fake data**
55
56 Suppose you have the following dataset::
57
58 Species_1 1 root superkingdom1 kingdom1 subkingdom1 superphylum1 phylum1 subphylum1 superclass1 class1 subclass1 superorder1 order1 suborder1 superfamily1 family1 subfamily1 tribe1 subtribe1 genus1 subgenus1 species1 subspecies1
59 Species_2 2 root superkingdom1 kingdom1 subkingdom1 superphylum1 phylum1 subphylum1 superclass1 class1 subclass1 superorder1 order1 suborder1 superfamily1 family1 subfamily1 tribe1 subtribe1 genus2 subgenus2 species2 subspecies2
60 Species_3 3 root superkingdom1 kingdom1 subkingdom1 superphylum1 phylum3 subphylum3 superclass3 class3 subclass3 superorder3 order3 suborder3 superfamily3 family3 subfamily3 tribe3 subtribe3 genus3 subgenus3 species3 subspecies3
61 Species_4 4 root superkingdom1 kingdom1 subkingdom1 superphylum1 phylum4 subphylum4 superclass4 class4 subclass4 superorder4 order4 suborder4 superfamily4 family4 subfamily4 tribe4 subtribe4 genus4 subgenus4 species4 subspecies4
62
63 Drawing the tree with default parameters (without changing anything in the interface) will produce this tree:
64
65 .. image:: ./static/images/t2ps_ideal.png
66 :width: 500
67
68 (for explanation of colors and numbers on the tree scroll to the bottom of this help section)
69
70 Here *Class* rank represent terminal nodes (leaves) of the tree because it is the default setting of the "*show ranks from root to*" drop-down. Changing the drop-down to "*Subspecies*" will produce this:
71
72 .. image:: ./static/images/t2ps_ideal_ssp.png
73 :width: 1000
74
75 --------
76
77 **Example 2: Fake data with missing nodes**
78
79 Real taxonomic datasets almost always contain empty nodes. These are represented with "**n**" as shown below::
80
81 Species_1 1 root superkingdom1 kingdom1 subkingdom1 superphylum1 phylum1 subphylum1 superclass1 class1 subclass1 superorder1 order1 suborder1 superfamily1 family1 subfamily1 tribe1 subtribe1 genus1 subgenus1 species1 subspecies1
82 Species_2 2 root superkingdom1 kingdom1 subkingdom1 superphylum1 phylum1 subphylum1 superclass1 class1 subclass1 superorder1 order1 suborder1 superfamily1 family1 subfamily1 tribe1 subtribe1 genus2 n species2 subspecies2
83 Species_3 3 root superkingdom1 kingdom1 subkingdom1 superphylum1 n subphylum3 superclass3 class3 subclass3 superorder3 order3 suborder3 superfamily3 family3 subfamily3 tribe3 subtribe3 genus3 subgenus3 species3 subspecies3
84 Species_4 4 root superkingdom1 kingdom1 subkingdom1 superphylum1 phylum4 subphylum4 superclass4 class4 subclass4 superorder4 order4 suborder4 superfamily4 family4 subfamily4 tribe4 subtribe4 genus4 subgenus4 species4 subspecies4
85
86 (here *phylum* for Species_3 and *subgenus* for Species_2 are unassigned)
87
88 A full tree for this dataset will look like this:
89
90 .. image:: ./static/images/t2ps_missing_nodes.png
91 :width: 1000
92
93 Missing nodes are simply omitted from the tree (there are no gray boxes corresponding to "n") but the branch length is maintained so that taxa belonging to the same taxonomic rank are always aligned with each other
94
95 --------
96
97 **Autoscaling the tree**
98
99 You can use the "*maximum number of leaves*" to restrict the tree to a specified number of leaves (external nodes). Using the following setting on the above dataset (note *show ranks from root to* set to *show entire tree* and *maximum number of leaves* is set *3*):
100
101 .. image:: ./static/images/t2ps_autoscale.png
102
103 will produce this tree:
104
105 .. image:: ./static/images/t2ps_autoscale_tree.png
106 :width: 1000
107
108 Here the tree is automatically trimmed at a taxonomic rank that will only have 3 outer nodes. This is very useful for initial evaluation of very large trees where you want to only see, say, 1,000 outer nodes at once.
109

112 **Explanation of phylogenetic tree markup**
113
114 Branches of the tree are colored according to the heatmap below. The "bluer" the branch the lesser the number of leaves it leads to and vice versa.
115
116 .. image:: ./static/images/t2ps_heatmap.png
117
118 Each node is labeled with taxonomic name and the number of tree leaves belonging to this taxonomic group:
