Oggetto: Re: [SPM] Combined extent-intensity thresholding
Hi Luca,
as usual ;) Christian has already implemented this and you can get it as
part of his cat12 toolbox, and also as a standalone version. Check his
website for details. Also search for TFCE on the list, there were some
messages on this topic.
Cheers,
Marko
