**What it does**

This tool reads a row (in a table) containing a collapsed sequence ID, and duplicates the .

.. class:: warningmark

You must specify the column containing the collapsed sequence ID (e.g. 15-4).

--------

**Example Input File**

The following input file contains two collapsed sequence identifiers at column 10: *84-2* and *87-5*

(meaning the first has multiplicity-count of 2 and the second has multiplicity count of 5)::


  23    0    0    0    0    0    0    0    +    84-2 ...
  22    0    0    0    0    0    0    0    +    87-5 ...


**Output Example**

After **uncollapsing** (on column 10), the line of the first sequence-identifier is repeated *twice*, and the line of the second sequence-identifier is repeated *five* times::

  23    0    0    0    0    0    0    0    +    84-2 ...
  23    0    0    0    0    0    0    0    +    84-2 ...
  22    0    0    0    0    0    0    0    +    87-5 ...
  22    0    0    0    0    0    0    0    +    87-5 ...
  22    0    0    0    0    0    0    0    +    87-5 ...
  22    0    0    0    0    0    0    0    +    87-5 ...
  22    0    0    0    0    0    0    0    +    87-5 ...


Uncollapsing a text file allows analsys of collapsed FASTA files to be used with any tool which doesn't 'understand' collapsed multiplicity counts.

.. class:: infomark

See the *Collapse* tool in the *FASTA Manipulation* category for more details about collapsing FASTA files.
