[…] & ITS2). Analysis was performed using Maximum parsimony (MP) to establish if a particular taxon formed a monophyletic clade. Prior to analysis, fasta files were converted into Nexus format using the Nexus Class Library []. PAUP was then used to implement Parsimony analysis. Support for branching patterns was assessed using the parsimony ratchet []. Consensus tree was generated from a set of the m […]

Some exceptions are the NEXUS methods provided by open-source toolkits such as BioPerl [], and by NCL [], for "NEXUS Class Library", a special purpose library written in C++. Most such implementations provide limited coverage of the NEXUS standard, and focus only on input and output of files, without providing […]
