I don't think I can do what I originally intended via the calculator filter due to the need to access the data in center[i][k] which is a data array in my script but the function parser won't know what to do with it. I was able to make some good progress using the programmable filter and the information on the wiki.
My main question at this point is how do I access the time data from the programmable filter? I am using multiblockdatasets. Thanks, Peter.
