Enter data in following ways:

To compare gene lists exported from GEO Profile neighbors, use this version.

To perform other list operations (sorting, merging, subtracting, etc.), use this tool.



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.
