　　大家帮看下主编是让修改成Letters to Editor还是别的？。经审稿后，主编回复
X
In view of the criticisms of the reviewer(s), I must decline the manuscript for publication in X at this time. However, if you wish to revise your manuscript thoroughly in accordance with the reviewers critiques and comments, I would be pleased to reconsider a new version of your article, if resubmitted as a Letter to the Editor after shortening the text and focusing on the most interesting data. It will then be considered a new submission to the Journal and will be subject to re-review.

各位高手帮我分析下主编是什么意思，是必须修改成Letters to Editor才重新考虑还是也可以不改成Letters to Editor啊，怎么断句的啊？
