when I run the code of runLinTurbine.py using openfast3.0, The following error message appears：

Hi @tatesnow, I ran this example just now with openfas3.0 and had no issue.
Can you run the command:
C:/Program Files/openfast/openfast_x64.exe ../../../data/NREL5MW/_5MW_Land_Lin_Trim2/000_ws14.0.fst
from the folder where the file runLinTurbine.py is located?
Make sure you have the latest dev version of pyFAST just in case, but most likely this is a system issue, where the executable path or the input file path is wrong.

okay, thank you very much!
