Description |
The sequence length is calculated by reading the sequence. Some libraries
(EMBL, SWISSPROT) have the length also in the first entry line so
to display the sequence length in these libraries, select the ID field.
Note that ranges can be combined: "300:!500 | !600:700" or "300:700 !
500:600" retrieve the
same set of sequences, namely all sequences from 300 to 500,
excluding 500, plus sequences from 600 to
700 where the 600 is excluded.
