Email to a potential master’s supervisor, initially responded but no reply after I sent my transcript
Any answer to this question would at best be a guess. 

It doesn't necessarily mean that he's not interested in it anymore. Perhaps the professor is just busy. Maybe he read your email, thought he'd get back to it later and then forgot about it as more emails piled on top of it. 

It's been a week since your last email. If I were you, I'd email him about this. That's the only way to know. Bite the bullet and send that e-mail now or a couple of days later asking if he is okay with your transcripts and if you could meet him as discussed. The worst that could happen is that he'll reject you. He won't be angered if you send him an email asking for clarification.
