nilearn.glm.first_level.first_level_from_bids#
- nilearn.glm.first_level.first_level_from_bids(dataset_path, task_label, space_label=None, sub_labels=None, img_filters=None, t_r=None, slice_time_ref=0.0, hrf_model='glover', drift_model='cosine', high_pass=0.01, drift_order=1, fir_delays=[0], min_onset=-24, mask_img=None, target_affine=None, target_shape=None, smoothing_fwhm=None, memory=Memory(location=None), memory_level=1, standardize=False, signal_scaling=0, noise_model='ar1', verbose=0, n_jobs=1, minimize_memory=True, derivatives_folder='derivatives')[source]#
Create FirstLevelModel objects and fit arguments from a BIDS dataset.
If t_r is None this function will attempt to load it from a bold.json. If slice_time_ref is None this function will attempt to infer it from a bold.json. Otherwise t_r and slice_time_ref are taken as given, but a warning may be raised if they are not consistent with the bold.json.
- Parameters:
- dataset_path
strorpathlib.Path Directory of the highest level folder of the BIDS dataset. Should contain subject folders and a derivatives folder.
- task_label
str Task_label as specified in the file names like _task-<task_label>_.
- space_label
str, optional Specifies the space label of the preprocessed bold.nii images. As they are specified in the file names like _space-<space_label>_.
- sub_labels
listofstr, optional Specifies the subset of subject labels to model. If ‘None’, will model all subjects in the dataset. .. versionadded:: 0.10.1
- img_filters
listoftuple(str, str), optional Filters are of the form (field, label). Only one filter per field allowed. A file that does not match a filter will be discarded. Possible filters are ‘acq’, ‘ce’, ‘dir’, ‘rec’, ‘run’, ‘echo’, ‘res’, ‘den’, and ‘desc’. Filter examples would be (‘desc’, ‘preproc’), (‘dir’, ‘pa’) and (‘run’, ‘10’).
- slice_time_ref
floatbetween 0.0 and 1.0, optional This parameter indicates the time of the reference slice used in the slice timing preprocessing step of the experimental runs. It is expressed as a fraction of the t_r (time repetition), so it can have values between 0. and 1. Default=0.0
Deprecated since version 0.10.1: The default=0 for
slice_time_refwill be deprecated. The default value will change to ‘None’ in 0.12.- derivatives_folder
str, Defaults=”derivatives”. derivatives and app folder path containing preprocessed files. Like “derivatives/FMRIPREP”.
- All other parameters correspond to a `FirstLevelModel` object, which
- contains their documentation.
- The subject label of the model will be determined directly
- from the BIDS dataset.
- dataset_path
- Returns:
- modelslist of FirstLevelModel objects
Each FirstLevelModel object corresponds to a subject. All runs from different sessions are considered together for the same subject to run a fixed effects analysis on them.
- models_run_imgslist of list of Niimg-like objects,
Items for the FirstLevelModel fit function of their respective model.
- models_eventslist of list of pandas DataFrames,
Items for the FirstLevelModel fit function of their respective model.
- models_confoundslist of list of pandas DataFrames or None,
Items for the FirstLevelModel fit function of their respective model.
