Hello,
I have an application that writes some meta data on the first three lines of a csv file and then xyz and then some quantity at those coordinates. How can one visualise this in paraview?
The TableToPoints filter doesnt recognise the first three lines and also I am not sure how I can assign the quantities in the 3rd or 4th colum to a subsequent field so i can plot histograms or PlotOverLine. Any help would be very much appreciated.
Cheers!

Hello,
Thank you for your reply. I managed to address this question. I went from csv to structured grid and point cloud and subsequently delauney 3d which worked quite well. I am now working to generate new data sets which may be large and I am wondering if the data should be written in a hdf5 container.
Finally I quite like the plot over line. I am wondering if its possible to fit the subsequent spectrum with routines from CERN ROOT. There is a python interface to ROOT. How would one integrate this into the analysis sequence?
Many Thanks
