Modify or use portion of inline variable %Name% from iterator

RobertRockwood — Thu, 06 Oct 2016 22:05:30 GMT

Hi-

I have a model using the 'Iterate Feature' tool. I am using the %Name% inline variable from the iterator to name my output files. The %Name% variable takes on the values "All_2014_06", "All_2014_07",.. etc. I would like to name my files with "Speed_2014_06", "Speed_2014_07", etc. instead... is there a way to alter the %Name% variable or only use a subset of the variable (the date portion) to do this?

I figured out the solution. You can use the 'Calculate Value' tool from the 'Insert'>>'Model Builder Tools' menu with the iterator 'Name' variable as an input. Adding the python script "%Name%"[4: ] will return the character string minus the first 4 characters. You can then use the result of the tool as your inline variable for naming.

It renamed the first file as 1 and took the name of first input file to rename the second file and so on.

Robert, that is exactly how to do it! The only thing I'd add is if the variable you are using is a pathname (likely to have \ characters in it) you need to escape it, for example:

r"%Path%" + ".tif"‍

Hi SUSHIL LAMICHHANE! I know this a really old post but I am experiencing this problem and wondering if you can help me? I have a model that creates a summary table for each unique record in a field. I am using the Calculate Value tool to remove spaces and other invalid characters from the %Value%; my output tables use %Name%. However, the name of the first output is "1" and the second table is what the first table should be and so on. Do you have a solution to this?
