+     <strong>Switching between mmCIF and PDB format for

+     from flat file and EMBL-PDBe web-service, as recommended by the
+     wwwPDB. If you prefer (for any reason) to download data as PDB files
+     instead, then first close Jalview, and add the following line to
+     your .jalview_properties file:<br />
 -    <code> DEFAULT_STRUCTURE_FORMAT=PDB </code>
++    <code> PDB_DOWNLOAD_FORMAT=PDB </code>
+     <br /> When this setting is configured, Jalview will only request
