<p>Pair style srp considers each bond of type <em>btype</em> to
|

be a fictitious “particle” of type <em>bptype</em>, where <em>bptype</em> is either
|
||||
the largest atom type in the system, or the type set by the <em>bptype</em>
|
||||
flag. Any actual existing particles with this atom type will be deleted
|
||||
at the beginning of a run. This means you must specify the number of
|
||||
types in your system accordingly; usually to be one larger than what
|
||||
would normally be the case, e.g. via the <a class="reference internal" href="create_box.html"><em>create_box</em></a>
|

or by changing the header in your <a class="reference internal" href="read_data.html"><em>data file</em></a>.
