@tharunpalla Did you test importing a sample file using the vortex user interface prior to attempting to script?

Yes, I had imported using the interface prior running through script.
If the user interface works, and the script does not, there is likely an issue with your script. Can you upload a sample of your data?
Just looking over the script you used to call importer
one issue potential issue I see is how you encoded the path to your clip shape.
clip_shp = 'C:\Users\chand\Downloads\HEC_DSS_Automation\Vortex\examples\src\main\jython\boundary.shp'
I would try again with either the the path encoded as a raw string or using unix-like path separators.
clip_shp = r'C:\Users\chand\Downloads\HEC_DSS_Automation\Vortex\examples\src\main\jython\boundary.shp'
#or
clip_shp = 'C:\\Users\\chand\\Downloads\\HEC_DSS_Automation\\Vortex\\examples\\src\\main\\jython\\boundary.shp'
#or
clip_shp = 'C:/Users/chand/Downloads/HEC_DSS_Automation/Vortex/examples/src/main/jython/boundary.shp'
You could check to make sure all the file paths you are specifying are valid using os.path.exists
before you call importer
.
assert os.path.exists(clip_shp), "Cannot locate clipping shapefile"

Please find the grib2 files attached. I am trying to convert the attached grib2 to dss grib2.zip
@tharunpalla Can you test the file separator suggestion the @danhamill provided. This is a very common issue in Jython scripting.

Hi @tombrauer and @danhamill, I have tried modifying the location string for shp file according to the suggestion but I am getting the same error.
Although, when I use a single variable as below
# variables = ['Total_precipitation_surface_1_Hour_Accumulation']
I get the output in the dss file. On contrary. If I use all the variables from the grib2 files, I get the error.
variables = set()
for file in files:
vars = DataReader.getVariables(file)
for s in vars:
variables.add(str(s))
variables = list(variables)
I think that makes sense.
Since .grib2 are self-describing data, you would only need select one variable (if they are all the same type of data).
Thanks for the clarification.
@danhamill @tombrauer I have one more query regarding the file conversion from grib2 to dss.
I want to convert a grib2 file which has precipitation data in UTC to DSS. I want to keep the time and date in the DSS into EST for the dss file using vortex. Could you please let me know if there is any way to change the timestamp in vortex?
I tried renaming the Grib2 files but the dss file remains same even after renaming.
Have a look at the time_shifter
utility.
Thank you.
Hi,
I am trying to convert grib2 rainfall data to DSS format. I have written a script to fetch the grib2 files from 'https://nomads.ncep.noaa.gov/cgi-bin/filter_nam_conusnest.pl?dir=%2Fnam.20220204' and then used vortex to convert to DSS files.
I am currently getting the following error:
Attaching my code to fetch and convert to DSS files.
