A new Sequence Retrieval System (SRS) interface for v.4 enhances bioinformatics research by supporting various terminals and client-server environments. This development ensures continued access to SRS data for a wider user base.

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Information Retrieval

Background:

  • The Sequence Retrieval System (SRS) is a vital tool for bioinformatics, enabling rapid data extraction from biological databases.
  • Previous SRS versions had user interfaces incompatible with newer SRS libraries, limiting access for users with simple terminals.
  • The ASCII WWW client LYNX was a workaround, but lacked the user-friendliness of dedicated interfaces.

Purpose of the Study:

  • To develop a new, user-friendly interface for Sequence Retrieval System (SRS) v.4.
  • To restore compatibility for users with character-oriented terminals (ASCII, VT100).
  • To extend SRS v.4 accessibility to graphics terminals and client-server environments.

Main Methods:

  • Developed a character-oriented SRS v.4 window interface using Tcl and Curses calls.

Related Experiment Videos

  • Implemented an X-Windows version utilizing the Tcl/Tk extension for graphics terminals.
  • Integrated a client-server capability using the Tcl TDP extension.

    • Main Results:

    • The new SRS v.4 interface successfully supports simple character-oriented terminals, maintaining the look and feel of SRS v.3.1.
    • The X-Windows and client-server extensions broaden SRS accessibility across diverse computing environments.
    • The interface is designed for library independence, aiming for compatibility with future SRS releases.

    Conclusions:

    • The developed SRS v.4 interface significantly enhances accessibility to crucial bioinformatics data.
    • It provides a robust and user-friendly solution for researchers using various terminal types and network configurations.
    • The new interface ensures continued utility of SRS as a major research instrument in bioinformatics.
