Several popular phylogenetic programs such as Paup *,〔(PAUP * ) — Phylogenetic Analysis Using Parsimony *and other methods〕 MrBayes,〔(MrBayes )〕 Mesquite, and MacClade〔(MacClade )〕 use this format. == Syntax == Command inside square brackets (and ) are ignored (comment). Each block starts with BEGIN block_name; and finishes with END;〔(Detailed NEXUS specification )〕An example for a simple DNA alignment would be: #NEXUS Begin data; Dimensions ntax=4 nchar=15; Format datatype=dna missing=? gap=-; Matrix Species1 atgctagctagctcg Species2 atgcta??tag-tag Species3 atgttagctag-tgg Species4 atgttagctag-tag ; End; 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nexus file」の詳細全文を読む スポンサード リンク
