I want to “label” each voxel to a specific parcel based on an atlas.

My question is, is there an exposed API that returns the parcel label of each voxel? In other words, which parcel a voxel belong to. I assume this is already implemented using `fit_transform`

and `plot_roi`

methods. The `fit_transform`

method averages the time-series of the voxels that belong to the same parcel. I am trying to track down `plot_roi`

to see how you map the voxels to parcels based on the center of mass coordinates but before going further I just want to make sure that there is an API exposed to do this?

If it matters, I use Yeo17thick atlas.

Code Example:

Assume I have a time-series matrix A_{t x v}, where `t`

is the time and `v`

is the number of voxels:

`I = get_parcels_labels(A, yeo['thick17']) #yeo['thick17'] is the file path of nifti of yeo`

The output, `I`

, will be a vector of size `v`

, where each element could have a value {0,1,2,…,16}. Which represents the parcels’ labels.
