<p class="MsoNormal">Hi Kenneth,<o:p></o:p></p>

<p class="MsoNormal">I took the Paraview training with you a couple of weeks ago in Denver. I have gotten many of the things working but I am still having trouble with one minor detail. I am writing a batch script to do post-processing without having to open
paraview GUI but I found a bug on the trace tool. It will not show the commands for saving data as .csv from the “Plot Over Line” filter. I found on the wiki how to do this by:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">writer=CreateWriter("myFile.csv",PlotOverLine1)<o:p></o:p></p>
<p class="MsoNormal">writer.FieldAssociation = "Points"<o:p></o:p></p>
<p class="MsoNormal">writer.UpdatePipeline()<o:p></o:p></p>
<p class="MsoNormal">del writer<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><a href="http://www.paraview.org/Wiki/ParaView/Python_Scripting#Exporting_CSV_Data">http://www.paraview.org/Wiki/ParaView/Python_Scripting#Exporting_CSV_Data</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Now this will only save my data for the first time step. I am interested in saving the data from the latest time step, or all time steps. If I try
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Writer.WriteAllTimeSteps = 1<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I will get the following error:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In /home/kgruchal/scratch/ParaView-3.10.1/Servers/Filters/vtkCSVWriter.cxx, line 80<o:p></o:p></p>
<p class="MsoNormal">vtkCSVWriter (0x2aab60975680): Unable to open file: /myFile.0.csv<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">How can I specify a time step to save the data?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I don’t know if you would know the answer for this or could point me in the right direction.<o:p></o:p></p>
