The GrADS code coverts all ensemble names to lower case. So that is probably the root of your problem. Ensemble names with upper case letters *do* work on my mac, however, because OS X is case neutral. It doesn't work on linux. I will update the documentation with that subtlety. <div>--Jennifer</div><div><br><div><br></div><div>You can have upper case letters in your ensemble name.

So you should make sure that all the files exist where they are expected to and that the names match up correctly with your template substitution strings in your DSET entry. Another check is to write a descriptor for one member, without the edef and substituting YSU for %e and make sure that works. <div> --Jennifer</div><div><div></div><div class="h5"><div><br><div><div><div>On Oct 5, 2010, at 12:43 PM, Jeffrey Duda wrote:</div><br><blockquote type="cite">Jennifer,<br>Here's what my actual control file looks like (not just the output from 'q ctlinfo'):<br> <br>dset ^summer_%e_%y4-%m2-%d2_%h2:%n2.dat<br>options byteswapped template<br>undef 1.e30<br>title OUTPUT FROM WRF V3.1.1 MODEL<br> pdef 325 249 nps 163.030 375.118 -97.1640 23.0459518<br>xdef 1021 linear -150.3 0.10381060<br> ydef 489 linear 12.4 0.10381060<br>zdef 26 linear 1 1<br>tdef 61 linear 00Z14JUL2010 60MN<br>edef 7 names YSU MYJ QNSE MYNN25 MYNN3 Pleim BouLac<br> VARS 20<br>U 26 0 x-wind component (m s-1)<br> V 26 0 y-wind component (m s-1)<br>W 26 0 z-wind component (m s-1)<br>WW 26 0 omega (Pa s-1)<br>PH 26 0 perturbation geopotential (m2 s-2)<br> PHB 26 0 base-state geopotential (m2 s-2)<br> P 26 0 perturbation pressure (Pa)<br>PB 26 0 BASE STATE PRESSURE (Pa)<br>Q2 1 0 QV at 2 M (kg kg-1)<br>T2 1 0 TEMP at 2 M (K)<br> PSFC 1 0 SFC PRESSURE (Pa)<br> U10 1 0 U at 10 M (m s-1)<br>V10 1 0 V at 10 M (m s-1)<br>QVAPOR 26 0 Water vapor mixing ratio (kg kg-1)<br>HGT 1 0 Terrain Height (m)<br> RAINC 1 0 ACCUMULATED TOTAL CUMULUS PRECIPITATION (mm)<br> RAINNC 1 0 ACCUMULATED TOTAL GRID SCALE PRECIPITATION (mm)<br>PBLH 1 0 PBL HEIGHT (m)<br>tc 26 0 Temperature (C)<br>slp 1 0 Sea Levelp Pressure (hPa)<br> ENDVARS<br><br>You can see that 'options template' and the 'edef' line is in there.<br> <br>Jeff<br><br><div class="gmail_quote">On Tue, Oct 5, 2010 at 11:34 AM, Jennifer Adams <span dir="ltr"><<a href="mailto:jma@cola.iges.org" target="_blank">jma@cola.iges.org</a>></span> wrote:<br> <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> <div style="word-wrap: break-word;">Hi, Jeff -- <div>You appear to have neglected to add 'options template' in your descriptor file.
