Hello, Without going in to too much detail I am trying to figure out how to designate an output name for a batch of raster files by only maintaining a certain portion of the original name. Is that possible? I know you can truncate text in other programs like excel by telling it how many characters to include, but as I am performing this on a batch of files my names will not be the same number of characters. One thing that may help is that the truncated part I wish to remove will always begin with "_ExG...." Here is an example: Current Name: 2012-10-12_38383C_ExG_RG_stacked.dat Wanted Name: 2012-10-12_38383C.JPG (here the .JPG is not to designate file type but just to match file names I already have) Any suggestions are greatly appreciated! Thanks, Allisyn
