Course about Cladistic Analysis by Dr. Goloboff in Barcelona, Spain.



Dear colleagues, 
  
Registration is open for the workshop "QUANTITATIVE CLADISTICS AND USE OF TNT - 
2nd Edition", June 29 - July 3, 2015. Instructors: Dr. Goloboff and Dr. Szumik 
(Conicet, Argentine). 
  
PLACE:  Facilities of the Centre de Restauració i Interpretació Paleontologica, 
Els Hostalets de Pierola,  Barcelona (Spain). 

WEBPAGE: http://www.transmittingscience.org/courses/phylo/cladistics/ 
  
PROGRAM: 
- Intro and Basics. Parsimony and phylogenetic systematics. Character 
optimisation and mapping. Most parsimonious reconstructions and specific 
changes. Input/output in TNT. Dataset formats. Using GB->TNT to create 
matrices. Instruction files. Options for graphic output (SVG, metafiles). 
Creation of “batch” files. Editing trees. Handling tree files. Groups of trees, 
characters and taxa.
- Tree calculation. Tree searches. Exact solutions, Wagner trees, 
branch-swapping. Local and global optima. Use of multiple addition sequences. 
Improving search strategies. Factors which affect the efficiency of 
tree-searches. Constraints and “timeouts”.
- Ambiguity and consensus; summarizing results. Zero-length branches and 
collapsing rules. Types of consensus and their use; improving consensus trees; 
supertrees. Pruned consensus. Comparison of tree-topologies; SPR distances.
- Character weighting. Successive and implied weighting. Auto-weighted 
optimization. Refining character weighting with blocks; taking into account 
missing entries. User-defined weighting functions.
- Group supports. Concept of group support. Bremer supports; how to calculate 
them; search of suboptimal trees. Problems with Bremer supports; absolute and 
relative Bremer support. Partitioned Bremer support and individual Bremer 
supports. Measures based on resampling; effect of search strategies and 
collapsing rules. Problems with resampling methods.
- Tree search in large and difficult data sets. Special search algorithms. 
Sectorial searches. Ratchet and drifting. Tree fusing. Combining different 
algorithms. Driven searches and stabilization of consensus.
 - Scripting. Automation of decisions to go beyond simple commands. Flow 
control. Decisions. Expressions, user variables, and internal variables. Design 
of simple scripts.
This course  is co-organized by Transmitting Science, the Institut Catalá de 
Paleontologia M. Crusafont and the Centre de Restauració i Interpretació 
Paleontologica. Places are limited and will be covered by strict registration 
order.  
 
Please feel free to distribute this information between your colleagues if you 
consider it appropriate.
