For Plexon that means that they are at 40kHz, for Neuralynx they are approximately 1MHz. This allows the different types of data acquired with the system (spikes, LFP, events) to be synchronized. </div><div><br></div><div>best regards,</div><div>Robert</div><div><br></div><div><br></div><div><br><div><div>On 31 Oct 2014, at 16:47, Dominic Depke <<a href="mailto:dominic.depke@ruhr-uni-bochum.de">dominic.depke@ruhr-uni-bochum.de</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div lang="DE" link="blue" vlink="purple" style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;"><div class="WordSection1" style="page: WordSection1;"><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;">Dear all,<o:p></o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><o:p> </o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span lang="EN-US">I have a question regarding the data structure of spikedata.<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span lang="EN-US">Especially I would like to ask how timestamps are encoded in the spike.timestamp structure (which timecode format e.g. clockticks, micro/mili/seconds) for further analysis in fieldtrip.<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span lang="EN-US"> </span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span lang="EN-US"> </span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span lang="EN-US">Thanks and best wishes,<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span lang="EN-US">Dominic<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span lang="EN-US"> </span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span lang="EN-US" style="font-size: 10pt; font-family: 'Courier New';">_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span lang="EN-US" style="font-size: 10pt; font-family: 'Courier New';">Dominic Depke, M.Sc.<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span lang="EN-US" style="font-size: 10pt; font-family: 'Courier New';">PhD student<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span style="font-size: 10pt; font-family: 'Courier New';">Institut für Physiologie I<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span style="font-size: 10pt; font-family: 'Courier New';">Robert-Koch-Straße 27a<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span style="font-size: 10pt; font-family: 'Courier New';">DE-48149 Münster<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span style="font-size: 10pt; font-family: 'Courier New';">Tel. : +49 251-83-58112<o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span style="font-size: 10pt; font-family: 'Courier New';">Email:<span class="Apple-converted-space"> </span><a href="mailto:depke@uni-muenster.de" style="color: purple; text-decoration: underline;"><span style="color: blue;">depke@uni-muenster.de</span></a><o:p></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><o:p> </o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><o:p> </o:p></div></div>_______________________________________________<br>fieldtrip mailing list<br><a href="mailto:fieldtrip@donders.ru.nl" style="color: purple; text-decoration: underline;">fieldtrip@donders.ru.nl</a><br><a href="http://mailman.science.ru.nl/mailman/listinfo/fieldtrip" style="color: purple; text-decoration: underline;">http://mailman.science.ru.nl/mailman/listinfo/fieldtrip</a></div></blockquote></div><br></div></body></html>
