[FieldTrip] Problem determining parcellations with HPC data

[Joan Rue Queralt]

Hello everyone!

I am dealing with HPC timeseries from rfMRI (dtseries.nii) data and I it has a 200 dimensionality ("parcellated”). I want to know which area of the brain corresponds to each parcel but I could not manage to find it out. When I read the file with ft_read_cifti in Matlab, it returns me the following struct: 

struct with fields
                  dimord: ‘pos_time'
                  time: [1×200 double]
                  hdr: [1×1 struct]
		  unit: ‘mm'
                  brainstructure: [96854×1 double]
		   brainstructurelabel: {1×21 cell}
                  dim: [91 109 91]
                  pos: [96854×3 double]
             	   transform: [4×4 double]
                  dtseries: [96854×200 double

But any of those variables is linking the parcel with any brain area. 

Thank you all in advanced!
