Alignment methods benchmark (pairwise ROI case)

In this tutorial, we compare various methods of alignment on a pairwise alignment problem for Individual Brain Charting subjects. For each subject, we have a lot of functional informations in the form of several task-based contrast per subject. We will just work here on a ROI.

We mostly rely on python common packages and on nilearn to handle functional data in a clean fashion.

To run this example, you must launch IPython via ipython --matplotlib in a terminal, or use jupyter-notebook.

Retrieve the data

In this example we use the IBC dataset, which include a large number of different contrasts maps for 12 subjects. We download the images for subjects sub-01 and sub-02. Files is the list of paths for each subjects. df is a dataframe with metadata about each of them.

from fmralign.fetch_example_data import fetch_ibc_subjects_contrasts
files, df, mask = fetch_ibc_subjects_contrasts(
    ['sub-01', 'sub-02'])

Extract a mask for the visual cortex from Yeo Atlas

First, we fetch and plot the complete atlas

from nilearn import datasets, plotting
from nilearn.image import resample_to_img, load_img, new_img_like
atlas_yeo_2011 = datasets.fetch_atlas_yeo_2011()
atlas = load_img(atlas_yeo_2011.thick_7)

# Select visual cortex, create a mask and resample it to the right resolution

mask_visual = new_img_like(atlas, atlas.get_data() == 1)
resampled_mask_visual = resample_to_img(
    mask_visual, mask, interpolation="nearest")

# Plot the mask we will use
plotting.plot_roi(resampled_mask_visual, title='Visual regions mask extracted from atlas',
                  cut_coords=(8, -80, 9), colorbar=True, cmap='Paired')

Define a masker

We define a nilearn masker that will be used to handle relevant data. For more information, visit : ‘http://nilearn.github.io/manipulating_images/masker_objects.html

from nilearn.input_data import NiftiMasker
roi_masker = NiftiMasker(mask_img=resampled_mask_visual).fit()
Prepare the data
 For each subject, for each task and conditions, our dataset contains two

independent acquisitions, similar except for one acquisition parameter, the encoding phase used that was either Antero-Posterior (AP) or Postero-Anterior (PA). Although this induces small differences in the final data, we will take advantage of these pseudo-duplicates to create a training and a testing set that contains roughly the same signals but acquired independently.

# The training set, used to learn alignment from source subject toward target:
# * source train: AP contrasts for subject sub-01
# * target train: AP contrasts for subject sub-02

source_train = df[df.subject == 'sub-01'][df.acquisition == 'ap'].path.values
target_train = df[df.subject == 'sub-02'][df.acquisition == 'ap'].path.values

# The testing set:
# * source test: PA contrasts for subject one, used to predict
#   the corresponding contrasts of subject sub-01
# * target test: PA contrasts for subject sub-02, used as a ground truth
#   to score our predictions

source_test = df[df.subject == 'sub-01'][df.acquisition == 'pa'].path.values
target_test = df[df.subject == 'sub-02'][df.acquisition == 'pa'].path.values

Out:

  source_train = df[df.subject == 'sub-01'][df.acquisition == 'ap'].path.values

  target_test = df[df.subject == 'sub-02'][df.acquisition == 'pa'].path.values

Choose the number of regions for local alignment

First, as we will proceed to local alignment we choose a suitable number of regions so that each of them is approximately 200 voxels wide. Then our estimator will first make a functional clustering of voxels based on train data to divide them into meaningful regions.

import numpy as np
n_voxels = roi_masker.mask_img_.get_data().sum()
print("The chosen region of interest contains {} voxels".format(n_voxels))
n_pieces = int(np.round(n_voxels / 200))
print("We will cluster them in {} regions".format(n_pieces))

Out:

The chosen region of interest contains 6631 voxels
We will cluster them in 33 regions

Define the estimators, fit them and do a prediction

On each region, we search for a transformation R that is either :
  • orthogonal, i.e. R orthogonal, scaling sc s.t. ||sc RX - Y ||^2 is minimized

  • a ridge regression : ||XR - Y||^2 + alpha *||R||^2 with a L2 penalization on the norm of R.

  • the optimal transport plan, which yields the minimal transport cost

    while respecting the mass conservation constraints. Calculated with entropic regularization.

  • we also include identity (no alignment) as a baseline.

Then for each method we define the estimator fit it, predict the new image and plot its correlation with the real signal.

from fmralign.pairwise_alignment import PairwiseAlignment
from fmralign._utils import voxelwise_correlation
methods = ['identity', 'scaled_orthogonal', 'ridge_cv', 'optimal_transport']

for method in methods:
    alignment_estimator = PairwiseAlignment(
        alignment_method=method, n_pieces=n_pieces, mask=roi_masker)
    alignment_estimator.fit(source_train, target_train)
    target_pred = alignment_estimator.transform(source_test)
    aligned_score = voxelwise_correlation(target_test, target_pred, roi_masker)
    title = "Correlation of prediction after {} alignment".format(method)
    display = plotting.plot_stat_map(aligned_score, display_mode="z",
                                     cut_coords=[-15, -5], vmax=1, title=title)
