Using Input names with iteration number

HolmSeifert — Fri, 25 Jun 2010 01:31:42 GMT

Hi everybody,

i have a question about using input names in modelbuilder.
Does anyone knows a clue how to integrate input names in the output Class?
I have some input raster´s with different input names. Every raster is proccessed thorugh several tools. In the end I want for every output raster its input name plus the iteration index n.
Example:
Input raster: Test
--> several processes
Output raster: Test0

Thanks

I'd have to see your model to be able to give you the exact syntax, but the basic idea is every "circle" part of ModelBuilder (the input/outputs) can be referenced via the name you set.

So, lets say you have copy features and it looks like this in the ModelBuilder window:

InputFeatures -- Copy Features -- OutputFeatures

If you are iterating over a bunch of FeatureClasses you already know about the "n".
So you can set the output to: %InputFeatures%_%n%
Which should give you something like:
roads -> roads_1
lakes -> lakes_2
rivers -> rivers_3

This help topic does a good job of explaining inline variables:

Hallo Kevin,

thanks. For Featgures it works.
But I want to use this for Rasters. I have tried the sequence exactly like the copy sequence, but everytime this failure occur:
"A locator with this name does not exist."
I just create a simple process.

Copy Raster -- %Input Raster%_%n%

For the Input Raster i have choosen 2 Raster Datasets stored in a gdb.
Can you help me?

thanks

Could you post your model or the picture of your model?

Hi Kevin,

here some data, a gdb, jpeg of the model and the failure message.
Hope you can find a solution.

thanks

Holm,

Thanks for providing that - it clears up my understanding of the question.
The information I originally providing you with wont work in this situation. Unfortunately the LIST doesn't provide the %n%. Additionally you can't control the output name with the input name via the inline variable with a list in the manner I proposed. (my apologies, I'm confusing functionality between 931 and 10).
The %n% count is only available with SERIES and with the Iterators built into ArcGIS 10.

It may only be possible to accomplish this with a script. I'll have to look into it a little more.

Hi Kevin

thanks a lot. I guess now its time to learnin g python. 😉
At the momemt i´m learning it.
Next time i going to create a python script which allows to import different data.
I guess the command woulkd be something about the cursor command.
Hoppefully i will create the script till tomorrow.

(But there is fifa soccer :D)

thanks and regards
