Hi Maria,
It fixes it, but I got another error:
atal:NclOneDValGetClosestIndex: finish coordinate index out of range, can't=
continue
fatal:Could not obtain coordinate indexes, unable to perform subscript
fatal:["Execute.c":8128]:Execute: Error occurred at or near line 71 in file=
rainfall_SPI.ncl
===
res@gsnCenterString = yyyymm({200007})
plot(0) = gsn_csm_contour_map_ce(wks,spi({200007},:,:), res)
==
How to get my coordinate indexes?

Hi Mamadou,
if you look at the documentation for yyyymm_time (http://www.ncl.ucar.edu/D=
ocument/Functions/Contributed/yyyymm_time.shtml)
you can see that the first and second argument have to be integers. Your yr=
Strt and yrLast are not integers. You can try
year = yyyymm/100
yrStrt = toint(year(0))
yrLast = toint(year(ntim-1))
and see if that fixes your problem.
Maria

I was trying to adapt the script from NCL scripts.
Thanks in advance
