Unclear answer from my prospective PhD Supervisor Is it positive to get the first reply from potential PhD Supervisor such as this: 

“Thank you for your interest in our PhD programme. I take it that you have looked at our admission criteria. If not, I suggest you do so. Otherwise, it will be nice to discuss your research idea.

I am a bit confused as to how to correspond to this reply, whether he interested or not?
I would guess that you received the professor's standard (if poorly worded) reply to prospective Ph.D. students. Of course, it is also possible that the professor looked at your CV or resume and doubts you fulfill the admissions requirement, but I would not read that far into the reply.

Regardless, be sure  to cover the following points in your reply:


Reiterate your interest in the program.
Indicate how you fulfill each criterion for admission to the Ph.D. program (attaching a resume or CV if you did not do so in your initial email).
Identify potential research threads that you would be interested in working on with the potential adviser.


The goal is to convert this cryptic email exchange into a productive correspondence that makes a potential supervisor excited to work with you. Addressing the three points above would likely achieve that goal.
