Ok, <div><br></div><div>I moved on a little..... Reading the output of the error reported in the previous mail, it says that it cannot find &quot;<span class="Apple-style-span" style="color: rgb(255, 0, 0); font-family: Courier; font-size: 12px; ">XArrayName</span>&quot;. Looking the original script you can see that it is needed for the definition of the plot area properties in the GUI.... I don&#39;t need it as I only want a csv file, so I commented out everything in that section. Running the script again it now complains about being unable to find &quot;<span class="Apple-style-span" style="color: rgb(255, 0, 0); font-family: Courier; font-size: 12px; white-space: pre-wrap; ">CreateWriter</span>&quot;. I need this to write the csv file so this error becomes fatal. </div>
<div>As this function should be included in the paraview.simple that I load at the beginning of the script (like explained in the manual), what I did was to go through all the functions in the simple.py file to locate it. Without any succes..... Then I went on with the brute-force approach and lauched:</div>
