<div dir="ltr"><div><div><div><div><div>Hi Rajasivaranjan,<br></div>I just pasted your script into a window here and used my own precipitation dataset and I get no errors whatsoever with NCL v6.2.1 or v6.3.0, so I am not sure what the problem is. <br><br></div>With regards to writing out netCDF files, there is an applications page devoted to examples of outputting .nc files. Go to the Examples page:<br><a href="http://www.ncl.ucar.edu/Applications/">http://www.ncl.ucar.edu/Applications/</a><br><br></div>and on the lower right hand side of the page there is a link entitled "Output netCDF". You will likely want to use method #1, as the inefficient method is sufficient for most applications. <br><br></div>Hope that helps. If you have further questions please respond to the ncl-talk email list.<br></div>Adam<br><div><div><br><div><br></div></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Jul 21, 2015 at 9:57 AM, Raja Sivaranjan <span dir="ltr"><<a href="mailto:rajasivaranjan92@gmail.com" target="_blank">rajasivaranjan92@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div><div><div>Dear all,<br><br></div>i'm trying to calculate spi for aphrodite from 1951 to 2007 using dim_spi_n function.
