I recently completed my PhD thesis with minor corrections and I presented most of the data in international conferences (posters and talks). Now I am focused on writing up the data for publication in a journal.
For the publication, 2 of 3 supervisors want me to change the direction of the analysis from data driven to theory-driven which will take several months and still might be rejected. They say the data is publishable as it is but that they want to fit the data to a theory that they are pursuing for other research grants (i.e. independently from me), and it may (or may not) lead to a better cited paper. I want to try to publish the data as it is, because that is what is in my thesis, I have presented these results before and they fit with my career interest.
I was wondering whether it is acceptable to push for publication how I want it, i.e. if we do not agree on this, who takes the lead decision? At the moment, I am in danger of not publishing this work because we cannot agree, but I don't feel this re-analysis is to do with the quality of my thesis work, and is more of a hidden agenda. My supervisors had involvement and that is not the issue. If I were still a PhD student, a re-analysis would likely happen (out of interest) but since I am a post-doc in another research group, I'm not keen on a re-analysis for the fun of it.
