+<p>
+Although BNC is a real-time tool, it can be run in post processing mode with reading data from a file. Use the following two command line options for that:<br><br>
+'--file' to enter the full path to an input file, and<br>
+'--format' to enter one of the format describing strings 'RTCM_2', 'RTCM_3' or 'RTIGS'.<br><br>
+Example:
+</p>
+<pre>
+./bnc --file FFMJ.dat --format RTCM_3
+</pre>
+</p>
+</p>
+<p>
+Note that when running in post processing mode BNC will use options for file saving, interval, sampling etc. from its configuration file ${HOME}/.config/BKG/BNC_NTRIP_Client.conf (Unix/Linux, see Config File example in the Annex) or from the register BKG_NTRIP_Client (Windows).
