Section 6-5: Find Sequences in the Databases with 'gopher' (via network)

[ Previous chapter ][ This chapter ][ Next chapter ] The program 'gopher' is a browsing tool which was primarily used for retrieving text information. Some servers allow you to search for keywords in a database and retrieve database entries from a menu presented afterwards. The keywords should be of high significance (e.g., an accession number).

SECURITY ADVICE: Databases accessed by GOPHER will nor run under the control of the local administration. Be aware that the result might not match the quality constraints applies usually. This is true in particular for non-academic sites.

Amongst others, the following 'gopher' servers are available:

 

  
Indiana:    GENBANK database
  
Houston:    PIR database
  

  
You must be connected to the Internet to contact a remote server. To connect to a 'gopher' server, you need to have the so-called 'gopher' client program. Both client and server software is available from the University of Minnesota, where 'gopher' was developed. Program versions for various platforms, including PCs and Macintoshes, exist. To start 'gopher' on a terminal or terminal emulator, type

% gopher

You can also try other programs like 'xgopher' or 'mosaic'. (If you have access to 'lynx' or 'mosaic' , you should use these programs instead of 'gopher'.) After you have started 'gopher', you should see a menu list. Use the cursor keys to select an option and hit <RETURN> to activate the field. In Europe, search for "EMBnet Information Resource", then "Database", and you will find the databases mentioned above.

To do a database search, select one of the databases and you will be prompted to enter a keyword. The hits will be presented as menu options. Selecting either of these gets you the text on the screen. After having inspected a text file, you can either continue with <RETURN>, save it by pressing the <S> key or mail it. Save it now, and then convert the format of the retrieved sequence as described in section "Reformatting Sequences" .

NOTE: The filename of the sequence saved will change during this procedure; see note in the reformat section .
