GCG is a research tool originally created at the University of Wisconsin, then developed and marketed by Genetics Computer Group, Inc. (GCG), now known as Accelrys Software Inc. It is a suite of tools that perform various protein and nucleic acid analyses. We provide a convenient list of the available GCG programs sorted by function. GCG provides access to a plethora of databases from within these tools, including but not limited to:

• EMBL - Nucleotide Sequence Database
• ENSEMBL - Genome Sequence Database
• PFAM - Multiple Sequence Alignment Database
• PIR - Protein Sequence Database
• SWISSPROT - Protein Sequence Database
• TREMBL - Computer-annotated supplement to Swiss-Prot
• GENPEPT - Transplated Coding Sequence Database
• NCBI - GenBank Databases

Access to GCG requires a CGB Research Computing account. For information on obtaining an account, please visit our account sign-up page. There are several ways to access GCG after you have an account:

Via the command line interface:

• Connect to research.cgb.indiana.edu via an SSH client (e.g. ssh username@research.cgb.indiana.edu)
• At the Unix prompt, type in 'source /bioportal/sw/pkgs/gcg/gcgstartup'
• You may now begin running the various applications (i.e. type 'map' to make a restriction map)

Via the graphical user interface:

• Make sure that you have an X Window Server installed for your operating system
• Connect to research.cgb.indiana.edu via an SSH client using X11 forwarding (e.g. ssh -X username@research.cgb.indiana.edu)
• At the Unix prompt, type in 'source /bioportal/sw/pkgs/gcg/gcgstartup'
• At the Unix prompt, type in 'seqlab'

Via the web interface:
