Apparently, one of the input arguments into the function zeros(), is either not a number, or infinite. This means, that either the quantity endsample-begsmaple+1 is behaving strangely, or that the hdr.NumberOfChannels is faulty, which would point to a problem reading in the header information from your datafile.</div><div><br></div><div>Best,</div><div><br></div><div>jan-Mathijs</div><div><br></div><div><br></div><div><div><div>On 17 Aug 2009, at 14:31, Roman Freunberger wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div lang="DE-AT" link="blue" vlink="purple"><div class="Section1"><div style="margin-top: 0cm; margin-right: 0cm; margin-bottom: 0.0001pt; margin-left: 0cm; font-size: 11pt; font-family: Calibri, sans-serif; "><span lang="EN-US">Hello,<o:p></o:p></span></div><div style="margin-top: 0cm; margin-right: 0cm; margin-bottom: 0.0001pt; margin-left: 0cm; font-size: 11pt; font-family: Calibri, sans-serif; "><span lang="EN-US"><o:p> </o:p></span></div><div style="margin-top: 0cm; margin-right: 0cm; margin-bottom: 0.0001pt; margin-left: 0cm; font-size: 11pt; font-family: Calibri, sans-serif; "><span lang="EN-US">I am a new fieldtrip user and would like to know how to read brainvision files that were exported as .dat into matlab with fieldtrip.
