To get this to work, use the Calculate Value tool. If your names are consistent as you say, either of these expressions would work.   r"%Name%"[-5:] # last 5 characters r"%Name%"[13:] # characters 14-end   and connect the output of the Calculate Value as a precondition to the tool where you will be using the output variable (with % around it, for example %Value%). %Value% is entered in the tool dialog where you had %Name% entered before. Hope this helps. UPDATE: probably a good idea to connect the variable Name to your Calculate Value tool in the model as a precondition to make sure you have the current value of %Name% used. Also documents the model nicely. I often rename the Calculate Value tool to something like Calculate Value end of Name to make it obvious what's going on in the model. ... View more

> I did do this for another raster but there was only one value and it was categorical - landuse type.  If you want to do it that way, the solution is to use the Reclassify tool to convert your soil types into integer codes (1,2,3,4..) (like your land use codes were), do your zonal statistics as table to find majority value, and then map the results (1,2,3,4..)  back to soil codes using an expression or lookup table. I know this seems unwieldy but is because ArcGIS rasters do not store text, they store integer or float numbers, so to do calculations on categorical data the values must  be integer, not text codes like "A/B".   ...

The Iterate Rasters iterator tool can loop through a wildcard match (Lep_jav_*.tif, for example) of rasters in a folder (and subfolders). You would do the iteration in a submodel and pass the multi output result to a driver model that creates the mosaic. David is correct that Python is more flexible with things like this, but ModelBuilder has some very powerful iteration capabilities, and if you know a little python you can make it even more powerful by using Python snippets in the Calculate Value tool to do things like manipulate file and path names. A quick tour of advanced techniques in ModelBuilder (ArcMap) Examples of using iterators in ModelBuilder (Pro) UPDATE: I could not resist figuring this out. I managed to do this with four models, a couple including a little bit of python (Calculate Value tool) to for example create the list if unique Genus_species pairs from the list of rasters and write it to to an in_memory table for later use (by the main Run All model). This model runs in Pro 2.8 (should work with all 2.x). UPDATE: I got some advice from my favorite ModelBuilder expert at Esri that in general iterators should be the first thing in the model, with nothing in front of it. This model did work, but probably this setup is not best practice. ... View more
