<br>
I am currently working on EOF analysis of SSTs in the North
Atlantic. While plotting the first 30 EOFs (polar plot) I for
the first time encountered the apparently infamous RPRAM -
ALGORITHM FAILURE error. I quickly found out that often enough
it has something to do with the contour intervals or levels and
thus played around with that for a while. But so far I've not
managed to plot all my 30 EOF patterns with one setting for the
contour levels and making all plots actually get drawn by ncl. <br>
<br>
I also found out, that the ARSCAM/ARPRAM bug has (according to
<a class="moz-txt-link-freetext" href="http://www.ncl.ucar.edu/prev_releases.shtml#ARSCAMARPRAMBugFixed5.2.1">http://www.ncl.ucar.edu/prev_releases.shtml#ARSCAMARPRAMBugFixed5.2.1</a>)
been fixed with NCL5.2.1 . So I wondered my problem might be or
if this is the reemergence of it? <br>
<br>
I have uploaded my data file and the script to the incoming ftp
directory under the following names:<br>
predictor01_sst_oct.nc (data, 50MB)<br>
SUPPORT_analyze_eof_sst.ncl (script, 4KB) <br>
<br>
-I am running ncl version 6.4.0<br>
-System type (don't 100% which part of this is relevant) Linux

Thanks for considering to help me out on this issue.<br>
I hope I did not forget to submit relevant information.<br>
