problem with arw2arl

[makr]

Hi,
I use arw2arl to convert WRF model data (one netcdf file, several hours, data every 60 minutes) to arl. I get the followinf error message:
Using an existing decoding configuration: WRFDATA.CFG
Output time interval not constant
Initial delta (min): 60.00000
Delta at period: 60.00001 4

Could you please give me some hints how to solve this?
Best,
Maciek

Please try deleting the WRFDATA.CFG file and run wrf2arl again.
If it still doesn't work please send me the WRFDATA.CFG file and the wrf netcdf file.
