Could somebody help me dealing with this problem?

it had repeated for hundreds of times,I didnt know what’s wrong

Hi @Jan_Lil,

To be able to help you, I would need you to post the commands you are using, and the kind of data you are trying to process. The same for this post, are both posts related? In the first one it seems that dwibiascorrect is not finding the data, am I correct?

Best regards,

Manuel
