Issue Reading MSG4

[WxmanJ]

I seem to be having difficulty reading the segments of Meteosat-11.

The traceback I receive is:

Below is my python script.

from pyproj import Proj

from satpy.utils import debug_on
debug_on()

FILES = glob("/root/msg_data/H-000*")

global_scene = Scene(reader='hrit_msg',filenames=FILES)

global_scene.load([0.6])
print(global_scene[0.6])
print(global_scene[0.6].info)

global_scene.save_datasets(writer='scmi', sector_id="Europe", source_name="AWIPS", filename='AWIPS_AII_MET11_SEVIRI_VIS006_GEOS_01.nc')

This issue has been resolved. It was a syntax issue regarding the reader.

[djhoese]

A syntax error in the reader? Or a syntax error in the way you were calling something?

[WxmanJ]

The way I was calling a feature.
