Other problems I noticed:</div><div>1. You are missing 'template' in your options entry. </div><div>2. The %mc template looks for a 3-character month abbreviation, so you need to rename dom2sept.dat to dom2sep.dat. </div><div>3. The date ranges in your files do not actually span the entire month, so starting with 00z31jul you will be seeing I/O error messages. Your file labeled 'sept' does not actually contain any data for September! Use %c instead of %mc and put some CHSUB entries to tell grads which time steps are contained in each file.</div><div>--Jennifer</div><div><div><div><br><div><br><div><div>On Jun 2, 2014, at 7:05 AM, Sara Fenech wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div dir="ltr">Dear all<div><br></div><div>I am trying to aggregate 4 .dat files using a data descriptor file using a single DSET entry and setting option to template.
