Conclusions
• Workflow for phylogenetic analysis
• New programs and resources
• ENA, PAUP, AliView, JModeltest, RAxML, Mr Bayes, FigTree, Simplot
• New things we have learned
• Unix commands
• Keep file names short but descriptive
• No spaces in file names
Recommendations
• Back-up
• Keep track of your work
• Keep proper file format
• Check the manual first
• Ask the experts
• ‘slack them’
