A software tool for extraction of annotation data from a PDB file

The rapid expansion in the amount of biological data being generated worldwide is exceeding efforts to manage analysis of the data. Annotation can be specified as any piece of information associated with an amino acid sequence. Annotation is a process of relating additional information with a particular point in a piece of information. The present task is completely based on the biological database Protein Data Bank (PDB). The main outcome of the work is to extract annotation field information from pdb files in suitable way and accumulate it in a condensed manner. During the course of work, the FASTA sequence representation is made and this sequence is used to generate the annotation id which is one of the major annotation field.
