<div dir="ltr"><p>Dear Sir,</p>
<p>I want to see linear trend (linear regression) in my data <a href="http://w.r.to">w.r.to</a> time as a an independent variable. After opening my ctl file and setting latitude, longitude and time, I was trying to use the udf function to see trend in temperature:</p>
<div>trend=linreg(tmp)</div>
<div> </div>
<div>But when I use this, GrADS simply quits without any message? I am using open GrADS Version 2.0.a7.oga.3.</div>
<div>Could you please guide me how to fit a linear trend line in the data? Also Can I see a spatial pattern of trend as well in GrADS?</div>
<div> </div>
<div>Thanks in Advance?</div></div>
