Recently one of my paper was rejected after review. The editor didn’t mention about the option of resubmission, just said:
It is challenging for us to envision a straightforward revision process to fully address these concerns, and therefore I am sorry that we can't offer to further consider this paper in its current shape.
I’d like to know whether I can understand this as a possibility of potential resubmission after substantial changes of my paper upon the editor and the reviewers’ request or not. I have a couple of good experiences with resubmission to the same journals, but at that time, editors always gave a clear option to resubmit my paper. This time, I’m not sure about whether the door to this journal is completely closed or not.
