Brief Overview

Reevaluate and visualize relationships using phylogenetic trees, Benzer plots, and circular plots.  

 
   
 


Project Materials

Noppadon: I wrote two PERL scripts to help reformat the files that JBenzer and GDE needed. The first one is "clustdist2benzer.pl" which takes the clustalw distant matrix (by the "clustaldist" option of Biology Workbench) and according to a given threshold, it produces an associated matrix that can be used with JBenzer. The second script is "benzer2gde.pl", which takes the jbenzer input file and transforms into a file that can be used with the GDE. Devi Prasad: I chose the enzymes used in the study, obtained the sequences from NCBI, constructed phylogenetic trees using Clustalw [Biology Workbench], converted the data back to distance mastrix ClustalDist[Biology Workbench]

Future Directions

1.Students are free to explore and modify the codes.
2.What is the right threshold for clustering using jBenzer and GDE, why ?
3.Reconstruct the phylogenetic tree from the combined matrix using tree drawing tools.
