What SSTV format is used for Portal images? Scottie 1? Robot 36?

First: I've captured audio which I believe contains an SSTV (Slow Scan TV) from wihin Portal. Playing this back into the RX-SSTV tool has no effect. Choices include Scottie 1 Robot 36, Martin 1 and many more. What RX Option should I select?

Second: is there a tool that can take a WAV file with SSTV, and decode it directly? So far I have found only tools that can listen to a microphone input.
