Hi,
I am trying to compute and plot the map of Standardized Precipitation In=
dex (SPI), but I got the following error:

here is the script :
prc = flt2dble(f1->var1)
pmsg = prc@_FillValue ; convenience
printVarSummary(prc)
printMinMax(prc,0)
runlen = (/12,24/)
nrun = dimsizes(runlen)

dimprc = dimsizes(prc)
ntim = dimprc(0)
nlat = dimprc(1)
mlon = dimprc(2)
yyyymm = f1->time
yyyymm = yyyymm/100
year = yyyymm/100
yrStrt = year(0)
yrLast = year(ntim-1)
nyear = yrLast-yrStrt+1
yyyymm = yyyymm_time(yrStrt, yrLast, "integer")
yrfrac = (/ yyyymm_to_yyyyfrac(yyyymm, 0.0) /)
prc&time = (/ yyyymm /)

copy_VarCoords(prc, spi)

gsn_panel(wks,plot,(/2,1/),resP) ; now draw as one plot
end do
end

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