Bioinformatics Division
(Sponsored by DBT, Govt. of India)

Under the BTIS net programme of DBT, a Bioinformatics Center titled "Distributed Information Sub-Centre (DISC)" has been established in October, 2002 in CSIR-IICB.



  • To build up information resource on biotechnology/genomics/proteomics and to develop relevant information handling tools and techniques.
  • To develop and conduct original research programmes on in silico biology (especially in the areas of genome analysis and metagenomics).
  • To provide a national bio-information network designed to bridge the interdisciplinary gaps in biotechnology information.
  • To facilitate and enhance application of bioinformatics in life science research and to provide bioinformatics related technical support services to the national community of users.
  • To organize long-term/short-term training programmes in diverse application of bioinformatics and computational biology.

In-House Software Development Activity

Novel algorithms and programs are being developed by the members of the centre for macromolecular sequence analysis.  Among the in-house software tools currently available at the Centre are :

(A) GCA & ClusterViz
A pair of programs, developed in C++ and Perl, for clustering of protein/gene sequences based on Markov-Chain Monte Carlo simulation and integrated visualization of the clusters with hyperlinks to their taxonomic distributions and functional annotations

(B)  SPAST (Substitution Pattern Analysis Software Tool)
An integrated software tool for quantitative analysis of (i) Nucleotide Substitution (synonymous/ non-synonymous/ non-coding) Patterns (ii) Amino Acid Substitution Patterns and (iii) changes in propensities for secondary structure formation in orthologous or paralogous genes/gene-products

A PC-based software tool, written in GWBASIC, developed for generation of Chaos Game Representation (CGR) patterns of different families of proteins.
