So I have been trying to get an article accepted since 2016. It is an article dedicated to a machine learning based prediction of a biological dataset. It was rejected 4 times. Today, on searching, I found that another paper has been published in Bioinformatics journal (Oxford) on 2018 April. This articles aim is exactly the same as mine. The feature set used is a superset of mine, only the classifier used is different than my current work. My work was rejected several times, so I have changed many things for every new submission. I also noticed that the issues that my previous reviewers had with my work, those same issues are still there in the Bioinformatics manuscript. This work in Bioinformatics has been done by 12 people while I am doing this work alone, with my advisor. Had it been accepted, it would have been the first paper with that aim. Now I feel terrible and I do not know how to deal with this professionally as well as emotionally. I suspect plagiarism by one of these many reviewers that this paper went through. I have been toiling for the last 2 years to get that work accepted. My advisor does not want to go for challenging plagiarism. What should I do?
On reading the manuscript I have found several flaws in it. The major flaw is its execution time is way more than my work. Now even if I try to get my work published, would anybody accept it since their work is already in a good journal like Bioinformatics?
I have tried to explain to myself that I have more work to publish, but it seems that I cannot. I am going through a lot of emotional turmoil. I have been crying incessantly for the past 24 hours... I am unable to understand how to get my positive attitude back. Please help...
