#summary generalized speciation duplication inference
-= Generalized Speciation Duplication Inference =
-
-== Purpose ==
-
-To infer duplication events on a gene tree given a trusted species tree.
-
-== Usage ==
-{{{
-java -Xmx1024m -cp
-path/to/forester.jar org.forester.application.gsdi [-options] <gene tree in phyloXML format> <species tree> <outfile>
-}}}
-=== Options ===
-
- * -g: to allow stripping of gene tree nodes without a matching species in the species tree
-
- * -m: use most parimonious duplication model for GSDI: assign nodes as speciations which would otherwise be assiged as potential duplications due tp polytomies in the species tree
-
- * -q: to allow species tree in other formats than phyloXML (i.e. Newick, NHX, Nexus)
-
- * -b: to use SDIse algorithm instead of GSDI algorithm (for binary species trees)
-
-==== Gene tree ====
-Must be in phyloXM format, with taxonomy and sequence data in appropriate fields ([http://forester.googlecode.com/files/wnt_gene_tree.xml example]).
-
-==== Species tree ====
-Must be in phyloXML format unless option -q is used ([http://forester.googlecode.com/files/species.xml example]).
-
-=== Output ===
-
-Besides the main output of a gene tree with duplications and speciations assigned to all of its internal nodes, this program also produces the following:
- * a log file, ending in `"_gsdi_log.txt"` ([http://forester.googlecode.com/files/wnt_gsdi_log.txt example])
- * a species tree file which only contains external nodes with were needed for the reconciliation, ending in `"_species_tree_used.xml"`
- * if the gene tree contains species with scientific species names such as "Pyrococcus horikoshii strain ATCC 700860" and if a mapping cannot be establish based on these, GSDI will attempt to map by removing the "strain" (or "subspecies") information, these will be listed in a file ending in `"_gsdi_remapped.txt"`.
-
-=== Taxonomic mapping between gene and species tree ===
-
-GSDI can establish a taxonomic mapping between gene and species tree on the following three data fields:
- * scientific names (e.g. "Pyrococcus horikoshii")
- * taxonomic identifiers (e.g. "35932" from uniprot or ncbi)
- * taxonomy codes (e.g. "PYRHO")
-
-
-
-=== Example ===
-`gsdi -g -q gene_tree.xml tree_of_life.nwk out.xml`
-
-
-=== Example files ===
- * [http://forester.googlecode.com/files/wnt_gene_tree.xml gene tree]
- * [http://forester.googlecode.com/files/species.xml species tree]
- * [http://forester.googlecode.com/files/wnt_gsdi_log.txt log file (output)]
