Hi Aris,

I think you are referring to the Beijing-Enhanced sample. That is a re-release of the original Beijing sample, but this now including IQ measures and DTI for a lot of subjects.

You can find the data here:
 
http://fcon_1000.projects.nitrc.org/indi... 

Also if you are on the main page: http://fcon_1000.projects.nitrc.org/inde...
- the 'old' 1000 functional connectomes data is located under the left brain
- newer INDI data can be found under the 'prospective' and 'retrospective' buttons. 

Cheers,
Maarten
