Thanks Vladimir! <div>(but does this mean I cannot convert my TF data at all, or i have to do this as a 'loophole' alternative...and then i get my TF data into the right format?)<br><br><div class="gmail_quote">On Thu, Nov 15, 2012 at 4:37 PM, Vladimir Litvak <span dir="ltr"><<a href="mailto:litvak.vladimir@gmail.com" target="_blank">litvak.vladimir@gmail.com</a>></span> wrote:<br>

Currently, I am using the new way to convert (previous version seems outdated 'nspm2ftrip') and I am hitting a wall: it says my data is not in the right format, ie: not freq data. But i know that it is...any advice would be much appreciated! Not to mention is warns me my data is not epoched when it is indeed so...</div>
