[求助] DNA序列上传NCBI问题求解

在NCBI上传动物COI序列后收到NCBI如下邮件,望有经验前辈赐教,该如何解决。本人比较外行,DNA提取扩增后都是由测序公司测序拼接的,对基因序列中存在的问题也不太清楚。NCBI邮件如下:
We have received the following 57 sequence submissions from you:

SUB7027792 :  (57)

Some or all of the protein coding sequences contain reading frame shifts
(insertions/deletions based on BLAST similarity search results and/or an
alignment), and/or have translations that show little or no similarity
to other proteins in the database.

This generally indicates problems such as:

  - errors in the nucleotide sequence
  - sequences have not been trimmed of low quality
  - problems with feature annotation which may be due to:
        translation in the wrong reading frame or on the wrong strand
        translation does not have the correct exon spans
        translation includes noncoding sequence, such as introns or UTR's
