How I can correct it? attachments are my bvals/bvecs; are they ok? could you provide a right example?

Your attahchment is OK.

However, according to the error message, the quantitiy of values in 'bvals' file is not equal to the quantity of columns in 'bvecs' file.

How many volumes of your data?

Best
