<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">We have recently experienced the same ‘buffer overflow problem’ with our system.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">In our case we think (after consulting with the manufacturer) that is a software related problem.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I do not understand what you mean when you say that the buffer overflow does not affect the data: again, in our case, the recording of the data is suspended for few seconds and then it resumes. So there are definitely
missing data. One solution for us was to make sure that there were no background processes running on the computer during recording (It seems you are using Recorder, so we probably did the same thing), but I would suggest you check with the manufacturer of
the system you are using. Please keep in mind that you need administrator rights on the computer in order to properly shut down other processes.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">We are still testing, but the problem is difficult to reproduce because it does not always happen.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I would very much appreciate if you could let me know how the problem evolve for you, in case you find a solution.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">Hi all,</span><span lang="EN-US"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">I have encountered a problem during our ERP experiments. During the recording, sometimes there would be an error message showing “data buffer overflow”. It seems that this error does not affect the
EEG recording, but the ERP marker recording would be messed up. When I tried to extract epochs from the raw data, the epochs are always less than they should be. I have already set up the computer system based on the recorder manual ('Configuring the Windows®
operating system for recording') but it didn’t help.</span><span lang="EN-US"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">Is anyone encountered this kind of problem before? How do you solve it?</span><span lang="EN-US"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">Thank you in advance.</span><span lang="EN-US"><o:p></o:p></span></p>
