<strong>Command</strong>s used in the TAXA Block<strong>Command</strong> <strong>Reference</strong>Window95/NTUNIX’C:\Tree Folder\treefile.trees’/home/users/Bob/tree_folder/treefile.treesUnlike the <strong>PAUP*</strong> convention for identifiers, underscores (_) are nottranslated into blanks. File-names containing blanks must be enclosedwithin single-quotes for the Macintosh and Window95/NT releases and arenot allowed under either the DOS or Unix releases. See your operatingsystem documentation for other file naming conventions.<strong>Command</strong>s used in the TAXA BlockThe TAXA block specifies information about taxa. In previous versions ofPAUP, both the taxa information and the character matrix were containedin the DATA block. However, in some instances the character matrix is notneeded, making the option to input only taxa labels useful. While it is stillpermitted, we strongly recommend against use of a DATA block ordefinition of taxa in a CHARACTERS or DISTANCES block because this willprevent some programs from extracting taxon information from the file.BEGIN TAXA;DIMENSIONS NTAX=number-of-taxa;TAXLABELS taxon-name taxon-name ...;END;DIMENSIONS must appear before TAXLABELS, and only one of eachcommand is allowed per block.DIMENSIONSThe DIMENSIONS command specifies the size of the data matrix. The syntaxis:DIMENSIONS NTAX = number-of-taxawhere number-of-taxa and are integer values.TAXLABELSThe TAXLABELS command defines taxa, specifies their names, anddetermines their order. The syntax is:TAXLABELS taxon-name1 taxon-name2 … taxon-name NTAX ;See "Taxon identifiers" on page 7 for rules on the format of taxon names.10 February, 2002 <strong>PAUP*</strong> <strong>4.0</strong> beta documentation
