Either Route or Switch would do it, but Switch is probably easiest. Take the output of your Selector and add 1 to it to get a number between 1 and n, for n the number of members in the imported group. Attach it to the first input to Switch. Take the Selected member and pass it to all of your image streams, and then send each result to successive inputs of Switch. Switch will choose the image stream selected by its first input and evaluate it, and ignore the rest.
Here's a example in .pdf form... I hope you can read it. Greg (See attached file: example.pdf) "Frederick R.

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 Frederick R.
