[ncl-talk] error in shapefile_mask_data.ncl

[Zhang, Xiao]

Hi

I use ncl 6.1.0 and would like to use function shapefile_mask_data. Since it has not been built in, I use the code provided from the website but got error message. Could you please help with this? Thank you!
"fatal:syntax error: line 158 in file ./shapefile_mask_data.ncl before or near :
          lat_sub :
------------------^

fatal:error in statement
fatal:syntax error: line 159 in file ./shapefile_mask_data.ncl before or near :
          lon_sub :
------------------^

fatal:error in statement
fatal:Syntax Error in block, block not executed"

Here are the codes I used.

part of my code

                shpfile   = "USA_adm_shp/USA_adm0.shp"
                opt             = True
                opt at return_mask = True

                 ;load self-define function
                load "./shapefile_mask_data.ncl"

                 land_mask_a1 = shapefile_mask_data(dif_a1(0,:,:),shpfile,opt)

Best,
Xiao
