    Hi jingchun liu,

    This type of error generally comes from contigs having a different naming convention in your reference files (Chr20 vs. 20). Could you take a look at this article about this issue as well as the suggestions in this previous forum post to see if it is helpful in adjusting the naming of your contigs?

    Kind regards,

    Pamela
