I'm currently using the csv writer to create a CSV file for subsets of data, then reading those csv files in to generate the numpy arrays for additional analysis, report generation, etc.

Is it possible to bypass the csv step, and directly convert the point data to numpy arrays?

A separate, but related question has to do with the file naming for CSV files. If I save data to slice.csv, Paraview will write to slice0.csv, (and sometimes slice1.csv, slice2.csv, etc.). Usually the other files are empty, but since the name passed to the csv writer is different from the name of the csv file that I have to read in, I'm having to change the name in the script. Is there an option to force Paraview to only write to a single CSV file? Is there a limit to the number of rows of data per file?

Thanks,

Tony
