   This tool extracts events from given populations from FLOCK or Cross Sample outputs.

-----

**Input**

FLOCK or Cross Sample output - a table of the fluorescence intensities for each event and the population associated with each.

**Output**

The input file filtered for selected populations.

-----

**Example 1**

*Input* - fluorescence intensities per marker and population ID per event::

   Marker1 Marker2 Marker3 Population
   34      45      12      1
   33      65      10      5
   19      62      98      2
   12      36      58      1

*Populations selected:* 2

*Method:* Keep only the selected populations

*Output* - fluorescence intensities per marker and population ID per event::

   Marker1 Marker2 Marker3 Population
   19      62      98      2

**Example 2**

*Input* - fluorescence intensities per marker and population ID per event::

   Marker1 Marker2 Marker3 Population
   34      45      12      1
   33      65      10      5
   19      62      98      2
   12      36      58      1

 *Populations selected:* 2

 *Method:* Remove the selected populations

 *Output* - fluorescence intensities per marker and population ID per event::

    Marker1 Marker2 Marker3 Population
    34      45      12      1
    33      65      10      5
    12      36      58      1
