<div>Hi ncl-users,</div>
<div> </div>
<div>I have encounted an error when reading a variable from an NC file.</div>
<div>the code is listed below:</div>
<div>;************************************************</div>
<div>load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"</div>
<div>;************************************************</div>
<div>begin</div>
<div> inp0 = addfile("/public/home/chenf/AHWRF/TEST/WPSwks.T02/<a href="http://geo_em.d01.nc" target="_blank">geo_em.d01.nc</a>","r")</div>
<div style="FONT-WEIGHT:bold"> lon2d = inp0->XLONG_M (Time|0, south_north|:, west_east|:)</div>
<div> printVarSummary(lon2d)</div>
<div>;************************************************</div>
<div>end</div>
<div> </div>
<div>the error message is:</div>
<div> Copyright (C) 1995-2013 - All Rights Reserved</div>
<div> University Corporation for Atmospheric Research</div>

<div> See <a href="http://www.ncl.ucar.edu/" target="_blank">http://www.ncl.ucar.edu/</a> for more details.</div>
<div>Segmentation fault (core dumped)</div>
<div> </div>
<div>The strange thing is when i'm reading the variable without any dimention name cited, the error disappeared.</div>
<div>The code changes into :</div>
<div>;************************************************</div>
<div>load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"</div>
<div>;************************************************</div>
<div>begin</div>
<div> inp0 = addfile("/public/home/chenf/AHWRF/TEST/WPSwks.T02/<a href="http://geo_em.d01.nc" target="_blank">geo_em.d01.nc</a>","r")</div>
<div style="FONT-WEIGHT:bold"> lon2d = inp0->XLONG_M</div>
<div> printVarSummary(lon2d)</div>
<div>;************************************************</div>
<div>end</div>
<div> </div>
<div>I don't understand why. It is very appreciate if anybody can tell me
the reason.</div>
<div>Thanks.</div>
<div> </div>
