A little question without your python code?

[lovechang1986]

I saw the source code in pysplit.
There is a function that aims to genarate the CONTROL file
and later run the hysplit model, hyts_std.exe.

but i run hyts_std.exe in cmd.exe while the CONTROL was existed.
it still need to give some parameters line by line?

how can i solve it?

I have never run hyts_std.exe directly because the generate_bulktraj() method in PySPLIT is more convenient and user-friendly.

Have you tried generate_bulktraj()? If you are having difficulties with this then make sure the hysplit keyword argument is pointing to the correct location of hyts_std.exe.
