Conditional Macros

I'm having a bit of trouble with macros and hoping to get some ideas. Currently, I have a process that looks like the image below. The loop collection uses the macro values to calculate attribute values which are added to the data set. The problem I'm having is that the macro values seem to change dependant on processing order and not be dependant on the throughput at all. I can eliminate the collection process, order the process execution to go tree by tree and simply have the final processes duplicated for each case in the tree. I thought this rather cumbersome and I'm hoping for a more elegant solution. Any suggestions?

Thanks,
Josh

    Hi,

    as always, actual process xml is probably more helpful. Currently I don't understand completely what you are trying to do; however concerning the macros it should be noted, that they are *global* variables, i.e. if they change in one branch or subprocess or anywhere else in the process, they also change at all other places.

    Best, Marius

    Maybe macro's aren't the way to go then.  Here's some example code of what I'm trying to do. I'm trying to calculate a value based off a coefficient that changes depending on which filter is applied. Is there another way of storing such a value? I know I could store a value for each example in the data set, but with several hundred thousand examples, thats a lot of unessessary data to store when I only need a handful of values stored.

    Thanks for your help.

    It's quite similar to Josh's original, but it doesn't use copies; it makes four bags into which the examples are apportioned according to their ingredients. On the side of each bag is written the recipe for the answer, so it's good for mass production, like cassoulet. My cooker does a million beans in a couple of seconds.

    Bon apetit!

    Thanks for the input. I like how you structured your filters, haddock. But I still have the problem with macros. So I've gone ahead and done as Marius suggests and stored the coefficients for each example. It certainly not efficient, but it works.

    Thanks again.

    Mmm, what's your problem with the macros?

    I'm using filters to branch a single data set into 32 sub sets. As the each set is filtered further I was hoping to store a coefficient using a macro. Some of these coefficients are shared among data sets as they branch out. The sample I showed illustrates this when four filters pass through two macros. Finally, the sub sets are collected and a process is looped over them that uses the macros to calculate a value. I was hoping for there to be a way to have the macros applied only to the data sets which pass through them. But it appears that is not possible, so I did as Marius recommended and simply got rid of the macros and stored a coefficient for each example in each data set.

    Hi,
    I was hoping for there to be a way to have the macros applied only to the data sets which pass through them. But it appears that is not possible,
    You were right to hope, it is possible, and that's exactly what my example did; I've expanded my code to show the coefficients as well, just to be clear.

    Good weekend!
