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
str
orpathlib.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
list
ofstr
, optional Specifies the subset of subject labels to model. If ‘None’, will model all subjects in the dataset. .. versionadded:: 0.10.1
- img_filters
list
oftuple
(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
float
between 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_ref
will 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.
