[FieldTrip] A query for solution

[Rajan Kashyap]

Dear all
I have used AAL atlas to parcellate my resting state fMRI data. So the
matrix is (Resting state Matrix =Spatial areas x Number of Volumes). I used
PCA on each subject and obtained the first PCA component. The matrix
becomes (Spatial Areas x 1).
I wanted to overlay the PCA component to the atlas so that I can visualise
the component across the spatial areas. I could see the function
*ft_datatype_parcellation* that could possibly project the data to the the
atlas. Am I right, or is their any other function. Can anyone help me with
the procedure?

Regards
