DAMBE

DAMBE的使用

下载地址 菜单栏File > Open Standrd Sequence File,此处是DNA,故而选择Non-Protein Nuc. Seq.单机Go!之后默认OK再默认Y

菜单栏Seq. Analysis > Measure Substitution Sturation (Nuc. seq. only) > Test by Xia et al.

根据你的结果判断是否适合系统发育

Interpretation of results:
               Significant Difference
               ----------------------
               Yes                 No
-------------------------------------------------------
Iss < Iss.c    Little             Substantial
               saturation         saturation
-------------------------------------------------------
Iss > Iss.c    Useless            Very poor
               sequences          for phylogenetics
--------------------------------------------------------------

#jModelTest的使用 下载地址,必须在java环境下运行。 菜单栏File > Load DNA Alignment选择你的文件。 菜单栏Analysis > Compute Likelihood Scores,因为用不到太多模型,也为了提高速度,将Number of Substitution Schemes改为3再点击Compute Likelihoods。 菜单栏Analysis > Do AIC calculations全选后点击Do AICc calculations选择ML的最适模型。 菜单栏Analysis > Do BIC calculations全选后点击Do BIC calculations选择BI的最适模型。 菜单栏Results > Show Results Table根据AICc和BIC查看最适模型。 菜单栏Results > Build HTML log保存文件。
