FileNotFoundError: [WinError 2] The system cannot find the file specified

[Yasminbr]

Hey,
I downloaded the whole git repository and while I run the Alignment. ipynb file I got the error FileNotFoundError: [WinError 2] The system cannot find the file specified

I see that ImageNames and pathNames are loaded, but still got this error.
trying to search in google didn't solve it.

Hope you can help with that. thank you.
