<li>Modify the <a class="reference internal" href="/wiki/display/ECFLOW/Glossary#term-suite-definition"><em class="xref std std-term">suite definition</em></a> file or python script</li>

<li>Load the <a class="reference internal" href="/wiki/display/ECFLOW/Glossary#term-suite-definition"><em class="xref std std-term">suite definition</em></a> file and begin the <a class="reference internal" href="/wiki/display/ECFLOW/Glossary#term-suite"><em class="xref std std-term">suite</em></a></li>
