NC to DFS2

[pradhancda]

Sir,

Would you please suggest a possible solution to this error.

Traceback (most recent call last):
File "E:\testing_automation\batch_scripts\ncmrwf_data_dfs2.py", line 63, in
dfs.write(filename=dfsfilename,
TypeError: Dfs2.write() got an unexpected keyword argument 'start_time'

thanking you,
Subhasis

Hi @pradhancda, could you let us know which version of MIKE IO you're using? And show a bit more of the script?

The error message "Dfs2.write() got an unexpected keyword argument 'start_time'" looks correct to me as this method has no argument "start_time".

Hi - you need to flip the data upside down not the axis.

Sir,
can i get one example ?

please...

Sir,

Again, I faced a problem during converting another wind file from nc to dfs2.

Output exceeds the size limit. Open the full output data in a text editor
