<div dir="ltr"><div>Thanks a lot for the help. I think Merge Blocks > Resample With Dataset > Python Calculator (or Append Attributes > Calculator) allows me to do what I originally asked for, although now I'm realizing the Python Calculator may not be enough to do the calculations I want. I had some questions regarding the Python Calculator and the Programmable Filter:<br>
<br></div><div>1. The data I'm looking at is from a transient simulation. If I wanted to standardize a parameter for each time step by dividing it by the standard deviation of the population for that time point, am I understanding correctly that I would either have to calculate the standard deviation first and then manually type in the number into the Python Calculator or use the Python Programmable Filter? <br>
<br>2. Additionally, I've been looking around and it seems the only way to perform a summing operation is to use the Programmable Filter. Is that correct?<br><br>3. Regarding both the Python Calculator or Programmable Filter, is there an easy way to tell which index corresponds to which input? I thought perhaps it had to do with just order you click the inputs in, but I'm not so sure about that. <br>

<br>
</div>How about using Append Attributes to combine the arrays of Resample<br>
With Dataset and the Source?<br>

<br>
</div>You can use Merge Blocks to combine all the blocks in a Multi-Block<br>
data set to an unstructured grid.<br>
<br>
