BMC GENOMICS

The editor is a great expert with over 40,000 citations and is very responsible. According to Research Square's data, the editor sent review requests to 20 people, and ultimately 16 people agreed to review. At that time, they were scared and thought they would be attacked and killed. The first review result was a major revision, which only included the opinions of two reviewers. One reviewer was almost accepting, with only one small suggestion and a few spelling corrections. The other reviewer was more strict, pointing out the flaws in the article and suggesting modifications. After carefully studying the second reviewer's opinions, additional data analysis, result organization, figure creation, and article modifications took a total of one month. The acceptance was received one week after the response.

The initial editor was very good, but after changing editors, I couldn't directly receive the emails sent back by the reviewers.
It took a total of 7 months, and we asked for reviewer comments. The editor-in-chief sent them to everyone, but another editor said a system change was needed.
Since I never received the reviewer comments, I resubmitted the paper as it was, and it was rejected.
They said it didn't fit the scope, and by this time, it was already the third submission.
Furthermore, this journal has a pre-submission quality control, which is just for formatting. It's usually a waste of time to make formatting changes before acceptance. Also, the standards for each quality control round were different. We had already passed round A, but then they wanted to make some suggestions in round B.
I sincerely do not recommend submitting to this journal unless your paper is very well polished, as the editing staff was previously very disorganized.
