This setup ensures the script is self-sufficient in managing its required resources. File loading: The script lists all files in the input directory and begins processing each one that matches the expected file extension (defined in step 1 as .raw). For each valid input file, the code: ...
to_datasetwill fail for unnamed DataArrays, but_to_temp_dataset()will succeed. It seems to me like we want lists of unnamed DataArrays to work (like in the first example), so call_to_temp_datasetwhen needed. Maybe@shoyerhas an idea on how to implement that cleanly. ...
