whose name starts with <tt>ab</tt> and
        ends with <tt>.pdb</tt>.  The hole procedure will
        be applied to each file in turn with the same setup conditions (initial
	point, sampling distance etc.).<p>

	As well as being able to read from multiple pdb files HOLE
	can now read from <small>CHARMm</small> .DCD format binary
	trajectory files.  Details of this option can be found
	by looking at the <a href="hole_d03.html#CHARMD">CHARMD</a>
	and <a href="hole_d03.html#CHARMS">CHARMS</a> cards.
