* -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 ====
* if the gene tree contains species with scientific species names such as "Pyrococcus horikoshii strain ATCC 700860" and if a mapping cannot be establish bases 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"`.
=== Example ===
-`gsdi -g gene_tree.xml tree_of_life.xml out.xml`
+`gsdi -g -q gene_tree.xml tree_of_life.xml out.xml`
