Hexamer likelihood

Do you ever heard about hexamer likelihood used to determine if a sequence is coding or not? In one of my assigments on my master of Bioinformatics there was a project to use hexamers instead. The hexamers are defined with 6 nucleotides on a sequence. The idea behind using hexamers is considering that in coding regions there is an influence of the previous codon to the next codon, whereas on the intronic or non-coding regions there isn't. The script works need three fasta files, the first one with intronic sequences, the second one with coding sequences, and the last one with sequences to analyze. All files must use the IUPAC code for sequences, and on the right frame. This is due to the way of signaling in which frame a sequence should be, which varies between programs and descriptions. It is also more difficult to calculate the best score for the unknown sequence, without presenting two scores or biasing for a training set. Assuming everything is on frame is safer and easi...

I'm sorry this month the news post will come with some delay, but there will be another post with it. If you like potatoes take one:

Bioinformatics News March

I must confess this month I thought I had any new to share but right after I published last post I found one which I saved for this month: The first epigenomic's map:( Spanish,   English) The logo of the consortium ( Roadmap Epigenomics Mapping Consortium )  involved on the Epigenomic's roadmap Sometimes people complain that bioinformaticians think that a gene is defined by a position in a chromosome or a genetic element, plasmid, mitochondrial chromosome, genome... I don't think so, many bioinformaticians are biologist who know how replication, transcription, and translation works molecularly. However the easiest way to work with genomes implies omitting it, and work with known sequences and suppose that they are transcribed and translated literally. With this step and the previously know Encode project we learn more about splicing and epigenomics and in the future we will see how this will change bioinformatics work.
