I dunno the answer to that. From all accounts, when vipec first came out it was the exact same. I dunno about the interoperability now.

Now, thinking about this logically. You need to load your link map into the vipec software for mixture map to do its corrections. Whether that can happen, I don't know. But I would think that the log file would be able to be loaded in either of the software packages. That would allow you see the mixture map but not have it do the corrections for you.
