<div>Andy,</div><div><br></div>thank you for your quick reply.<div><br>I am using Paraview 3.8.0 which is the latest binary in the Ubuntu repos. I chose to install that without compiling from source as I was rushing (I know, it sounds weird... but). Do you believe that the problem is build-related?</div>
<div><br></div><div>However, reading the errors that you get I don't see anything that I can visualize in my output which is as follows (Python shell)</div><div><br></div><div><meta name="qrichtext" content="1"><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><style type="text/css">

It looks like a complain about the server, not about my script though.... in fact, if comment out the writer part, leaving only the "trace" recorded set of operations, it spits out the very same error. Moreover, the Paraview output doesn't show any output at all (except for the usual a complain about the qt4 that is not related).</p>
<p style="margin-top: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; ">Do you see any evident problem in the script syntax in the writer section? For example references to the wrong source, etc?</p><p style="margin-top: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; ">
Or do you believe that it is a problem related to the Paraview/Python installation (or whatever..). </p><p style="margin-top: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; "><br></p><p style="margin-top: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; ">
Another point.... does the "PlotOverLine2" influence the results? I recorded the trace making a second POL that automatically got labeled as #2... if I run it at startup it executes perfectly fine so I don't think that the problem is here too.</p>

If you're running the python script in the paraview gui sometimes the messages are printed out to the python shell. What version of paraview are you using? <br><br>I'm running paraview from the head of the repo. The output I get from the OutputMessages window is:<br>

Hello everybody,<div><br></div><div>I've been using Paraview for quite a long time but I didn't need the python scripting up to now.</div><div>I want to execute a series of plot over line in numerous points and different time steps so it is nothing</div>
<div>I can afford to do manually.</div><div>Looking on the net I was able to find out how to record a macro and how to create a writer so I</div><div>ended up with this script:</div><div><br></div><div>--------------------------------------------------------------------</div>

<div><br></div><div>If I'm not mistaken, this should write a csv.csv file in my home folder but it doesn't write anything.
