Thank you for the PR @Gjacquenot, Could you share your specific use case for passing the turbsim BTS file as an argument to the routine?

Typically, users would want to load in the TurbSimFile class so that all the content of the BTS file can be read in; and then the content either visualized or modified.

I have tested it with the wind bts file from r-test repository

Then the command is the following, it sums up the content of the two Python pandas dictionaries

cd openfast_python 
python3 -m openfast_io.turbsim_file wind.bts

@Gjacquenot, thanks for your reply. I think we are missing some context here. Could you explain why you want to do this as opposed to loading the TurbSimFile class and exploring the metadata that way?

[Gjacquenot]

Well, I just wanted to update the default entrypoint that tries to load a non existing BTS file. Now, the entrypoint allows to load a bts file and get some infos on it. I agree that the main usage is still to load the main class from another file.

Looks good for now. Will update the summary in main() to use __repr__ in #2361
