Transforming the PhD thesis to a paper to publish and iThenticate I want my PhD thesis findings to be presented as a scientific pager and get it published in a journal which uses "iThenticate" as plagiarism detection software. When I present my findings, it's unavoidable that I'll use many exact sentences and exact findings from thesis to the paper. So, as I have already published my thesis to the university (the thesis is not available to the public so, only me, university and the turnitin only knows that the thesis exists in this world), will the iThenticate detect my own thesis as self plagiarism? Does "iThenticate" go through the academic thesises submitted via "turnitin" to the university? Because iThenticate only state following as their databases which is not clear for me

The only option I see is pay $100.00 USD and buy their one paper credit and check if my thesis is detected by them, but it's a waste of money just to check. Can somebody tell me if they go through thesises? And any other advises for me?
iThenticate might check your paper against your thesis.  Many universities send theses to Proquest, which shares them with iThenticate, as you mentioned.  However, you have no problem.  Most journals allow you to publish parts of your thesis as journal articles. If iThenticate tells the journal your paper is a copy of your thesis, they will ignore this information.  

You should check the policies of the journal before you submit your paper to it.
