area.txt in structural connectivity input

[Jeehye An]

Hi,

I am importing DTI-based structural connectivity data into TVB. I already have text files for weights, tract_lengths, and and centers. 

One of the (optional) inputs is area.txt (in mm^2). Could someone explain to me what this is supposed to be? I'd understand mass/volume per region but I'm not sure about area!

hi,

This would be the cortical area as reported by e.g. FreeSurfer.  It is not used for the simulation, so you can set it to ones for each region if you don't have that information. 

cheers,

Marmaduke

Hi there,

Following with these lines, which are the files .txt used in the simulation and I need to provide? I have a connectome but now I need to transform it to use it in TVB, but I don't have all the other files.

Thanks,

Esteban
