Hi Saurabh,

I have attached a modified version of your script, “depth_trend_line_mod.ncl”. One major change is that it now checks the output of the regline_stats() function to make sure the result is not a missing value.

The issue I found was that during the first iteration of your loop (i=0), the value returned by regline_stats() contained a missing value and did not have the “b95” attribute.

Also, I chose to explicitly declare temp (“temp = new(1, double)”) before the loop, instead of implicitly declaring it inside the loop (“temp = regline_stats(time,ts(i,:))”). When regline_stats() experiences an error, the value returned is a float instead of a double, which causes issues in later iterations of the loop (with an error such as “fatal:["NclVar.c":1390]:Assignment type mismatch, right hand side can't be coerced to type of left hand side”).

I hope this helps!
Kevin

I want to save the upper and lower bound value of b95 but somehow the function is not working. Please help me out for this. I am attaching the data file and the code that I am using.
