**What it does**
        
This tool extracts a segment from a molecular dynamcics trajectory (i.e. performs a slice). 

_____


.. class:: infomark

**Input**
 
       - Trajectory file (xtc, dcd)
     
In addition, a start frame and end frame have to be specified for the output trajectory, 
as well as a value for the 'stride' (to save only every nth frame in the output file).
_____

        
.. class:: infomark

**Output**

       - Trajectory file (xtc, dcd) extracted from the input file.
