<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class="">Hello everybody,<br class=""><br class="">I’m trying to run a sample regression script from the NCL pace (<a href="https://www.ncl.ucar.edu/Applications/Scripts/regress_3.ncl" class="">https://www.ncl.ucar.edu/Applications/Scripts/regress_3.ncl</a>) I’m using the assigned data (air.sig995.mon.mean.nc). <br class="">I have the 6.1.2 version of NCL and I loaded the following commands:<br class="">load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl" <br class="">load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl" <br class="">load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl" <br class="">load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/shea_util.ncl” <br class=""><br class="">The script works fine until the line where it’s supposed to perform the linear regression: rc = regline_stats(year, xavg). <br class="">Here I get the error message:<b class=""> "fatal:Undefined identifier: (regline_stats) is undefined, can't continue”</b><div class=""><br class=""></div><div class="">Does anyone have an idea how I can run the<b class=""> regline_stats </b>command? It does’t seem to be loaded. Since I'm using a NCL sample script I'm assuming it has nothing do with the code itself.</div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">Cheers,</div><div class="">Angie</div><div class=""><br class=""></div></body></html>
