SEQUENCE LENGTH WARNING

Attempts to generate very long sequences (e.g. a million characters or longer, depending on the computer performance) may make the web browser jerky or even frozen. Significant time (a second per each 100,000 characters or so, depending on the computer) will be required to complete such tasks.

SEQUENCE FORMATTING

By default, the generated sequence contains no line breaks (it is one line text even though it is displayed as a justified block). To truly justify the sequence into a text block, regularly spaced line breaks must be inserted. This is done by the "Format Output" operation (if set to do so). The "Clean Sequence" operation will do just the opposite, i.e. remove all numbers, spaces, and line breaks to get a one-line sequence.
The "Format Output" and "Clean Sequence" functions will also process any external sequence pasted in the Sequence Output field.
