The Wisconsin Package GCG is a software suite that contains over 130 sequence analysis tools. It was developed by the Genetics Computer Group in Madison and is now maintained and distributed by Accelrys. It can be accessed remotely from any networked computer. There are three different interfaces for accessing GCG:

All three applications are installed at UCR on the UNIX server cache.ucr.edu where they share the same sequence databases.

The basic Command-Line interface provides access to all ~130 GCG programs, which are started from an X terminal like PuTTY (PC) or X11 (Mac OS X). Its scriptability allows repetitive analyses.

To start GCG from your X terminal application (see above), type the following command:

  • $ gcg

SeqLab is a point-and-click X Windows interface to almost all GCG programs. Its centralized main window and UNIX based file management facilitates numerous tasks at once.

To start SeqLab from your X terminal application, do the following:

  • From a PC start X-Win 32 first. Then type:
  • $ seqlab &
