What did not work? What error did you receive?

I tried to follow the example from
https://www.harrisgeospatial.com/docs/envireprojectglttask.html

e = ENVI()

infile = 'OR_ABI-L1b-RadC-M3C01_G16_s20181062057233_e20181062100006_c20181062100050.nc'
Raster = e.OpenRaster(infile)

Task = ENVITask('ReprojectGLT')

Task.Input_Raster = Raster[0]
Task.Latitude_Raster = Raster[1]
Task.Longitude_Raster = Raster[2]

then the error message appears
% Attempt to subscript RASTER with <INT ( 2)> is out of range.

if you can provide an example code/script showing how to reproject GLT with GOES-16 image (instead of VIIRS data as on the webpage above), that would be great

Specifying the Raster[0], [1] and [2] depends entirely on how many rasters are opened when you use OpenRaster. You would need to do a help on the raster object and determine if indeed, raster[0] is your radiance data, raster[1] is latitude, raster[2] is longitude, etc.

Were you able to open the .nc file with Open As->Scientific Formats which opens the Scientific Browser? If so, then you can save this as a template and when you use OpenRaster, use your template to open the file so you know which rasters are in your file and you are passing the correct information to the GLT.
