Abstract:
En este trabajo, hemos creado un programa que permite el ensamblaje de novo
de secuencias nucleotídicas. El programa ha sido escrito en lenguaje de programación
Perl y utiliza una estrategia basada en la representación de la secuencia mediante un
grafo bidirigido de De Bruijn. A partir de secuencia... Ver más
In this work, we have written a computer program for the de novo assembly of
nucleotide sequences. The program has been written using the Perl programming
language, and uses a strategy based on bidirected de Bruijn graphs. Starting from short
nucleotide sequences (the reads), the program produces a FastA file containing the contig
sequences and a dot file that allows one to visualize the relationship among the different
contigs. We have used our program in order to evaluate the effects of several parameters
(such as the k-mer length, the sequencing coverage or the sequencing error rates) on the
quality of the resulting assemblies. In addition, we have found that De Bruijn graphs are
an interesting tool that might facilitate the identification of novel splice variants. Finally, we
think that our program is a powerful teaching tool that will help the students to investigate
the relationships between graph theory and genomics
