I have 8000 protein sequences that I want to cluster based on similarity (not identity) and select the longest representative sequence from each cluster. I checked several tools like HiFix, SiliX, ClusTR but could not find the optimal solution. I want to do clustering as like CD-Hit does to reduce dataset but based on sequence similarity rather that sequence identity.

So you want to group by functional similarity?
You can do this based on physio-chemical properties of the amino acids. You translate each amino acid into 5 different metrics and then use Discriminant Analysis of Principle Components to cluster based on these properties.Described here:http://www.biomedcentral.com/1471-2148/12/68
I can provide you with file formats/tips if needs beLast edited by JackieBadger; 07-09-2013, 03:55 AM.

Thanks, it seems interesting and I planned to use it later as currently I am not focused on functional similarity!

The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...-

The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...-
