Hello,

I have some basic questions about accessing indices of data items. I know param viewer allows you to extract the branch number inside {}, but how do I convert that number to an integer?

In the attached image you see three data branches {1} {4} {7} with integers [50] [50] [50]. The integers will rarely be the same and singular. For this particular case, the goal is to create the following splitting masks…

{1}[50]

{4}[50]

{7}[50]

…but really the definition needs to be able to be robust enough to create masks like:

{1} [50, 157]

{4} [50, 157]

{7} [50, 220]

{10} [50, 180]

{13} [50, 220]

from branch numbers {1} {7} {10} {13} and integers within each branch [50,157] [50,157] [50,220] [50,180] [50,220].

I’m looking at this post and I saw HS_Kim used expression editor to build the splitting mask. I feel like this is the method I should explore more, but I have yet to find a forum post that explains the ins/outs of expression editor like David’s “Data Selection Rules” so I’m fumbling in the dark as to what {} and mean inside the expression editor and how to call items within data branches and lists.
