Did you check in your reader that you get properly the file name of the first file ? When you switch back to the first time ? <br><br>Seb<div><br><div class="gmail_quote">On Fri, Sep 7, 2012 at 1:04 PM, Joe Ping-Lin Hsiao <span dir="ltr"><<a href="mailto:phsiao@cs.unc.edu" target="_blank">phsiao@cs.unc.edu</a>></span> wrote:<br>

mismatched source name. (Later I figure out that I don't need a gui<br>
xml for the reader to run.) Now I can load data without crash.<br>
<br>
But the problem remains. The animation plays fine at the first time.<br>
After it plays to the end, I click the 'Go back to the first frame'<br>
button, but the rendering still stays at the last frame even though in<br>
the information tab it says it's at frame 0. Am I missing something?<br>
