I downloaded the gribb file from weather.gov and I get this error when Input parameters : {"operation":"parse","discipline":-1,"dataExport":true,"category":-1,"filePath":"latest.grib2","reduceFilePath":"reduced.grib2","exportType":3,"maximumNumberOfMessages":2147483647,"geoFilter":{"minLat":0,"maxLat":36000000,"minLong":-9000000,"maxLong":9000000},"surfaceFilter":{"type":0,"scale":0,"value":0}} Error when parsing a message, Template number not supported: 41 [ ]

@gocluster , could you send me a link to a file where this is happening so that I can debug and fix this?

Thank you. MRMS_PrecipFlag.latest.grib2.gz And this is where I got the data from http://mrms.ncep.noaa.gov/data/2D/

http://www.nco.ncep.noaa.gov/pmb/docs/grib2/grib2_doc/grib2_temp5-41.shtml It seems that the data is encoded as a PNG. So we need to, first decode the PNG, and then treat as template 5.0 (http://www.nco.ncep.noaa.gov/pmb/docs/grib2/grib2_doc/grib2_temp7-41.shtml)

@gocluster what kind of data should we get from this file?
