The developers acknowledge the tremendous services provided by the National Centre for Biotechnology Information [NCBI]. Almost all the databases are downloaded from the NCBI. ftp://ftp.ncbi.nlm.nih.gov/.

We also acknowledge the hard work and efforts of team at Bioinformatics Centre, National University of Singapore, Singapore from where we derived the intron database. http://intron.bic.nus.edu.sg/introndb/introndb.html

Phylodendron version 0.8d is an excellent web server for drawing phylogenetic trees, which has been developed by D.G. Gilbert. Biology Dept. Indiana University We duly acknowledge his efforts in developing such a tool. http://iubio.bio.indiana.edu/treeapp/

MVIEW is a reliable tool for viewing alignment from BLAST and other programs. We acknowledge the efforts of the team ( Brown, N.P., Leroy C., Sander C ) which developed this tool. http://mathbio.nimr.mrc.ac.uk/~nbrown/mview/

CLUSTALW executables were obtained from ftp site of European Bioinformatics Institute ftp://ftp.ebi.ac.uk/pub/software/unix/clustalw/.

Jalview is a multiple alignment editor written by Michele Clamp entirely in java. It was initially to be used as a visualization tool for the Pfam CORBA server and client at the EBI but is available as a general purpose alignment editor. For more details go to http://circinus.ebi.ac.uk:6543/jalview/

The ProDom database contains an automatic compilation of homologous protein domains. 390 ProDom families were generated automatically using PSI-BLAST with a profile built from the seed aligments of Pfam-A 4.3 families. PRODOM can be downloaded from ftp://ftp.toulouse.inra.fr/pub/prodom/current_release/

The FASTA package was downloaded from ftp://ftp.virginia.edu/pub/fasta/. Compares a protein sequence to another protein sequence or to a protein database, or a DNA sequence to another DNA sequence or a DNA library. Has a complete suite of programs for similarity searching.
