Phreatoi20220525.nex 
    Mesquite data file that contains all data from the DELTA taxonomic database that were used for data presentation, organization, analysis, as well as trees resulting from all analyses. For Mesquite version 3.70; Maddison WP, Maddison DR. 2021. Mesquite: a modular system for evolutionary analysis.  Version 3.6 University of British Columbia & Oregon State University., http://www.mesquiteproject.org/ 

The DELTA database is still being edited and changed so it is not included here

Phreatoi20220525.tnt -  the TNT data file generated by Mesquite
Analyses were performed using TNT-64bit, version 1.5, Goloboff PA, Catalano SA. 2016. TNT version 1.5, including a full implementation of phylogenetic morphometrics. Cladistics 32: 221-238.
Note: TNT counts zero as a number so the first tree, taxon or k paramter is 0, the second is 1, the third is 2 and so on  

TNT Scripts were written or modified for this project by George D. F. Wilson. They were run using the console in Ubuntu 20.04 but should work using the console version of TNT in other operating systems available from http://www.lillo.org.ar/phylogeny/tnt/. I recommend using the console because it allows you do to multiple analysis with one script. 

Each script has a banner that explains what is being done. If this fails to appear the first time, enter n and restart the script

These are easily modified in a text editor to change the analysis
 -- tnt.run : standard run of tnt. 
 -- tnt-jacK.run :  symmetric jackknife analysis with concavity parameter, select file, concavity and prob parameter  
 -- piwe_rangeK.run : A range of concavity parameters are selected at the beginning and run sequentially
 -- setk_trans.run : Modified from setk.run by Salvador Arias, Instituto Miguel Lillo, San Miguel de Tucuman, Argentina
 -- aquickie_bt1000.run : Modified from the standard script distributed with TNT with more iterations of jackknifing
