Thank you very much for bringing attention to this issue. As you mentioned, the error stems from the presence of "b" values in the CSV files. To address this, we have developed a small script that replaces the "b" values with 0. You can locate this script in the root of the repository under the name b-error-fixer.ipynb. We greatly appreciate your contribution and assistance in resolving this issue. Thank you once again.
