=== Options ===
* -g: to allow stripping of gene tree nodes without a matching species in the species tree
- * -b: to use SDI algorithm instead of GSDI algorithm
- * -m: use most parimonious duplication model for GSDI: assign nodes as speciations which would otherwise be assiged as unknown because of polytomies in the species tree
- * -q: to allow species tree in other formats than phyloXML (Newick, NHX, Nexus)
-
-==== Species tree ====
-In phyloXML format (unless option -q is used), with taxonomy data in appropriate fields. Must be rooted, polytomies are allowed.

+ 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 ====
-In phyloXML format, with taxonomy and sequence data in appropriate fields. Must be rooted an binary (no polytomies).
