8.13.15.10. nilearn.glm.first_level.run_glm¶
- nilearn.glm.first_level.run_glm(Y, X, noise_model='ar1', bins=100, n_jobs=1, verbose=0)[source]¶
GLM fit for an fMRI data matrix
- Parameters
- Yarray of shape (n_time_points, n_voxels)
The fMRI data.
- Xarray of shape (n_time_points, n_regressors)
The design matrix.
- noise_model{‘ar(N)’, ‘ols’}, optional
The temporal variance model. To specify the order of an autoregressive model place the order after the characters ar, for example to specify a third order model use ar3. Default=’ar1’.
- binsint, optional
Maximum number of discrete bins for the AR coef histogram. If an autoregressive model with order greater than one is specified then adaptive quantification is performed and the coefficients will be clustered via K-means with bins number of clusters. Default=100.
- n_jobsint, optional
The number of CPUs to use to do the computation. -1 means ‘all CPUs’. Default=1.
- verboseint, optional
The verbosity level. Default=0.
- Returns
- labelsarray of shape (n_voxels,),
A map of values on voxels used to identify the corresponding model.
- resultsdict,
Keys correspond to the different labels values values are RegressionResults instances corresponding to the voxels.
