Hi Dominik<BR>
<BR>
I do not have Matlab to test, but there should be no issue of "endianness" as I work on Windows and use PC-based editors. The file type does not seem to be the issue, but more the data within (just guessing).<BR>
<BR>
I have tried all the data type variants without success: other than being able to read the points in.<BR>
<BR>
Didn't seem to make much odds using xyzc (0 1 2 3) or (0.0 1.0 2.0 3.0)<BR>
<BR>
Do you have an example raw data file? It would be so much more convenient to be able to load up data via CSV (but that currently doesn't work).<BR>
<BR>
What would be the best way of loading data into Paraview that does not require any programming or major work?<BR>
<BR>
