For anyone whose brain is still in their head and/or doesn't have 7T data, there is also FreeSurfer[1] to play with. I only really know about the physics of MRI, so I admit I don't fully understand what the advantage of this project is against other work; I assume it would have a lot to do with the fact that the data is so much higher resolution and can identify finer structure within the brain.

Dang this sucks, I had all the files from my brain MRI when I got Dengue Fever but my laptop recently got stolen out of my car and the CD they gave it to me on was in it. This would have been fun to mess with. The MRI facility is in another country so not sure how easy it would be to get them to send me the data again (although they should I gave them 3k dollars).

  Just ask them. I don’t know which country it’s in but they may be legally obligated to send it to you (maybe for a modest fee), regardless of which country you’re from. They usually are in developed countries but YMMV everywhere else.

  Every country is different but I'd be surprised if they don't still have it. The irony is they will probably still have to burn it on a CD and mail it to you. Good old DICOM!

    Yeah I'm going to try and get it now. That sucks though, because that laptop was the last device I had that had a cd drive! Maybe an excuse to finally get one of those modded vintage Thinkpads with modern mobo/cpu.

      There's always USB CD/DVD drives you can use, or I've even seen external USB enclosures for Desktop and Laptop CD/DVD drive form factors which you can just shove one into.

        Ironically an external USB DVD reader will probably be cheaper than getting your hands on that CD...

  Almost certainly you can probably get it from them again.

> admit I don't fully understand what the advantage of this project is against other work Replying to myself here; seems that the combination of being ex vivo and 7T means that the resolution increase over a typical in vivo patient scan is really really tremendous since your dead brain is happy to remain completely still through multi-hour sequences. The resolution you can get is primarily dependent on field strength but like many things in signal processing, you can trade integration time for higher resolution to a point. So this dataset is at about 100micron while 7T in vivo can only get down to maybe 300-1000micron (best case depending on patient movement)
