<div dir="ltr"><div>Hi Joe,<br><br></div><div>As far as I can tell, ncl_filedump composes an NCL script on the fly that gets executed against your file. That script normally gets placed in a temporary file in the /tmp directory; ncl_filedump helpfully (in most cases!) cleans the script up afterwards.<br><br></div><div>More to your issue however, I would suggest doing a plain old "ncl_filedump <a href="http://20150304_0200.nc" rel="noreferrer" target="_blank">20150304_0200.nc</a>" and inspecting that output to determine if indeed something is corrupt/degenerate about the latitude and any other variables you might be interested in. If everything looks good, then perhaps you could send us the file to look at, via the FTP instructions following (and send a quick note once its there).<br><br></div><div>Rick<br></div><div><br><b>You can ftp larger datasets and files to:</b>

<br>
I am working on a research project using netCDF files. However, when i search certain .nc files for the variable latitude using the command "ncl_filedump -v latitude <a href="http://20150304_0200.nc" rel="noreferrer" target="_blank">20150304_0200.nc</a>” I receive the following errors:<br>
<br>
warning:FileReadVar: latitude contains a 0 length dimension<br>
fatal:NclReturnValue: Incomplete information to create return value from builtin function<br>
fatal:["Execute.c":8575]:Execute: Error occurred at or near line 84 in file /tmp/tmp22049.ncl<br>
<br>
fatal:["Execute.c":8575]:Execute: Error occurred at or near line 197 in file /tmp/tmp22049.ncl<br>
<br>
I have tried searching for the temp22049.ncl on the machine but cannot find it. I am working the supercomputer at the University of Oklahoma with unix, NCL, and other packages installed.<br>
<br>
Any help on this error message would be much appreciated.<br>
<br>
Sincerely,<br>
Joe Puma<br>
