SLIM longitudinal study matrix/3D-tensor structure FC dosenbach160

Dear community,

I would like to know if anyone know about this database http://fcon_1000.projects.nitrc.org/indi/retro/southwestuni_qiu_index.html. They have processed the fMRI and they report somewhere parcellation dosenbach 160. The problem is when I open the file of one functional conectivity matrix there are 3 matrices. I don’t understand. Isn’t it supposed to be one matrix NxN ROIs?

Thank you for all the help in advance.

Rene Andrade.

I don’t know if this is the rigth forum.
