[opendx-general] Need a dx box that acts as an "if-then" control

[Frederick R. Phelan Jr.]

Below is what I want to do, but I can't figure out the part in the question marks.

I start by running Import through both a Selector and a Select. I can then change the desired component coming out of Select, simply by clicking the Selector. That much is fine.

The problem is that based on what is selected, I want to do the imaging differently. So, essentially, I need a box that acts as an "if-then" control; specifically, if "select" = "comp1" go to Image Stream 1, else if "select" = "comp2" go to Image Stream 2, else go to Image Stream 3.

I have tried Route, but it expects all three image streams at once, so it does not work. Can this be done? Right now I just manually change the connection from the select to the desired imaging stream, but it seems like there ought to be a more intelligent way.


File Selector
  |
Import ------>Selector
  |             |
Select<----------
  |
???? if select = "comp1", go to IS1
     else if select = "comp2" go to IS2
     else go to IS3 ????
 
  |                 |                 |
[Image Stream 1]  [Image Stream 2]  [Image Stream 3]

Thanks,
Fred Phelan
