In the appendix of the EDIT manual of the SynAmps2 it says that:</div><div>
<div class="page" title="Page 337">
<div class="layoutArea">
<div class="column"><p><span style="font-size: 10.000000pt; font-family: 'Verdana'">Actual data begins immediately after the header for .EEG, .AVG, and .CNT files. Thus, the
offset to the beginning of data is 900 (=sizeof(SETUP)) + 75 (=sizeof(ELECTLOC)) *
erp.nchannels bytes. </span></p>
</div>
</div>
</div></div><div>If your header information is lost completely for this dataset, it should start after the number of bytes indicated by the above formula. Maybe you can find more relevant information in the SynAmps2 manual.</div><div><br></div><div>Hope that helps,</div><div>Kathrin</div><div><br><blockquote type="cite"><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;"><span style="font-family:'Helvetica'; color:rgba(127, 127, 127, 1.0);"><b>From: </b></span><span style="font-family:'Helvetica';">Matt Craddock <<a href="mailto:matt.craddock@uni-leipzig.de">matt.craddock@uni-leipzig.de</a>><br></span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;"><span style="font-family:'Helvetica'; color:rgba(127, 127, 127, 1.0);"><b>Subject: </b></span><span style="font-family:'Helvetica';"><b>[Eeglablist] .CNT files with no header</b><br></span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;"><span style="font-family:'Helvetica'; color:rgba(127, 127, 127, 1.0);"><b>Date: </b></span><span style="font-family:'Helvetica';">October 24, 2014 at 7:04:36 AM EDT<br></span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;"><span style="font-family:'Helvetica'; color:rgba(127, 127, 127, 1.0);"><b>To: </b></span><span style="font-family:'Helvetica';">"<a href="mailto:eeglablist@sccn.ucsd.edu">eeglablist@sccn.ucsd.edu</a>" <<a href="mailto:eeglablist@sccn.ucsd.edu">eeglablist@sccn.ucsd.edu</a>><br></span></div><br><br>Dear list,<br><br>During a recent recording with the Neuroscan SynAmps2 system, the Scan software crashed straight to desktop when I pressed Stop Recording. While the EEG data was clearly recorded, the resulting .CNT file has no header information, so I can't load it using the standard EEGLAB commands. Anybody got any suggestions? I can get most of the header information from similar files, but what's not so easy to figure out is how many frames there are exactly, and where exactly in the file they start.<br><br>Thanks,<br>Matt<br><br>-- <br>Dr. Matt Craddock<br></blockquote></div><br></body></html>
