[Carlos Chagas Filho's choice of biological physics: reason and motivations].

This study investigates the reasons and motivations behind Carlos Chagas Filho's choice to abandon the line of study developed by his father, Carlos Chagas, and brother, Evandro Chagas, both of whom had very successful careers researching tropical diseases. Though Carlos Chagas Filho first worked on anatomical pathology, he suddenly shifted his attentions of the physicochemical aspects of vital processes. Extant sources show that a number of unforeseen circumstances took place from early on in Chagas Filho's education.

A new set of bioinformatics tools for genome projects.

A new tool called System for Automated Bacterial Integrated Annotation--SABIA (SABIA being a very well-known bird in Brazil) was developed for the assembly and annotation of bacterial genomes. This system performs automatic tasks of assembly analysis, ORFs identification/analysis, and extragenic region analyses. Genome assembly and contig automatic annotation data are also available in the same working environment.

A System for Automated Bacterial (genome) Integrated Annotation--SABIA.

Unlabelled: A web-based software suite, SABIA (System for Automated Bacterial Integrated Annotation), is described that provides a comprehensive computational support for the assembly and annotation of whole bacterial genomes from the data derived from sequencing projects.

Availability: Both SABIA and supplementary materials are available at http://www.sabia.
