<p class="MsoNormal"><span lang="EN-US">Hello Everyone, <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I keep running into an error trying to open up biosemi bdf data. The error is copied below. However this error is very inconsistent, so I can get the error, then run the code again changing nothing and not get the error.
This seems to be the case with multiple bdf dataset so it it’s that one is corrupted or something. Does anyone know what might be causing this inconsistent error and how I can avoid it?
