Five types of extractions are proposed.

• Simple : Just extract the sequences or subsequences of list.
• Translate to protein : Useful for protein-coding subsequences only. Will translate them in protein on the fly using the adequate reading frame and genetic code. Does nothing on non-protein coding sequences.
• Extract fragment : Allows to extract any part of the sequence(s) in list. Such part is specified in the dialog box appearing later following the syntax suggested by these examples:

  
  132,1600        to extract from nucl. 132 to nucl 1600 of the sequence
  -10,10          to extract from 10 nucl. BEFORE the 5' end of the sequence
                  to nucl. 10 of it. Useful only for subsequences, and produces
                  a fragment extracted from its parent sequence.
  e-20,e+10       to extract from 20 nucl. BEFORE the 3' end of the sequence
                  to 10 nucl. AFTER its 3' end. Useful only for subsequences, and 
                  produces a fragment extracted from its parent sequence.
  -20,e+5         to extract from 20 nucl. BEFORE the 5' end of the sequence
                  to 5 nucl. AFTER its 3' end.
  

• Extract feature : Allows to extract any feature listed in the feature table of sequences in list. Select the desired feature in the scrolling list appearing later. Meaningful only for parent sequences (subsequences have no feature table) and to access those features that do not correspond to a subsequence (e.g., EXON, mRNA, PRIM_TRANSCRIPT, REP_ORIGIN).
• Extract feature region : Allows to extract a region surrounding a feature of sequences in list. Select next the desired feature as explained above and the desired fragment around this feature as explained for option extract fragment above.

1. remove to exclude members of the list
2. retain to keep members of the list

• The list content appears in a scroller, and desired elements can be selectively removed/retained by clicking on them.
• After clicking on button done the edited list appears as a new list in panel Current lists

• >1000 to retain sequences of length >= 1000
• <5000 to retain sequences of length <= 5000

• 1/juin/93 to retain sequences updated after June 1st, 1993
• 31/dec/89 to retain sequences updated before Dec 31st, 1989
