EXON _5: Initializing the BCR's sequence analysis software and the On-LineHelp screens. GCG Genetics Computer Group "the Wisconsin package" -At the "%" prompt, type "setgcg" and hit return -At the "%" prompt, type "gcg" and hit return -You should see the GCG banner appear along with a listing of the current databases available to the BCR locally. -At the "%" prompt, type "genhelp" and hit return. -The system will display the on-line help topics for every program available in the GCG suite. -At the "%" prompt, type "genmanual" and hit return. -The system will display the on-line help topics for every program available in the GCG suite but arranged by function. Extended GCG is a series of "unofficial" releases of programs which complement the official suite. These programs were developed in several EMBL labs. -You MUST have the GCG programs initialized BEFORE trying to start EGCG. -At the "%" prompt, type "setegcg" and hit return. Next type "egcg" to get things going.

From the workstations, type "netscape &" to start the UNIX Netscape program. Open the following URL "http://trex.musc.edu/" for on-line help and access to various BioMolecular links. In addition, the WWW2GCG mode of access to the GCG programs is available from this site.
