Hello<br><br>I have tried replacing the windows path structure with Unix style with no effect so I am not sure what the issue is ?<br><br>I can upload the whole sample file to test if that would help?<br><br>As I can tell the the script will search for the delimiter of ">" to find each segment which is clear from the input file, but for whatever reason it seems not to be able to even locate the file.<br><br>Cheers<br><br>Lester<br><br><hr id="stopSpelling">From: robert.maynard@kitware.com<br>Date: Fri, 11 Mar 2011 14:09:31 -0500<br>Subject: Re: [Paraview] Getting line data into Paraview 3.10.0<br>To: sebastien.jourdain@kitware.com<br>CC: lester_anderson1963@hotmail.com; paraview@paraview.org<br><br>I recommend always using Unix style paths when trying to open files even when on windows.<br><br><div class="ecxgmail_quote">On Fri, Mar 11, 2011 at 2:05 PM, Sebastien Jourdain <span dir="ltr"><<a href="mailto:sebastien.jourdain@kitware.com">sebastien.jourdain@kitware.com</a>></span> wrote:<br>

It seems that your command to open the file is wrong..<br>
