If the error is reproducible, could you please send the shortest possible script to illustrate the error and the output from ncdump -c on your netcdf file? <div>Jennifer</div><div><br><div><br><div><div>On May 13, 2008, at 9:21 AM, Petroski, Tom ((MLCI)) wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><o:smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place"><o:smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="PostalCode"><o:smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="State"><o:smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="City"><o:smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="address"><o:smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="Street"><div class="Section1"><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><font size="2" color="blue" face="Arial"><span style="font-size: 10pt; font-family: Arial; color: blue; ">Jennifer,<o:p></o:p></span></font></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><font size="2" color="blue" face="Arial"><span style="font-size: 10pt; font-family: Arial; color: blue; "><o:p> </o:p></span></font></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><font size="2" color="blue" face="Arial"><span style="font-size: 10pt; font-family: Arial; color: blue; ">Output from q dims is below.
