Function to generate a trial_data object from a BIDS-compliant folder

Description

Function to generate a trial_data object from a BIDS-compliant folder

Usage

generate_trial_data_from_bids(bids_dir, modality = "func", task_name = "ridl")

Arguments

bids_dir	a directory containing BIDS-compliant processed data for analysis
modality	the subfolder within bids_dir that contains data of a certain modality. Almost always 'func', which is the default.
task_name	the name of the task, which is appended with type
type	at present, always 'task' to denote this part of the BIDS filename... Not totally sure what else it could be
suffix	an optional suffix in the expected filename (just before the file extension)

Details

The files should generally have a name like sub-220256_task-ridl3_space-MNI152NLin2009cAsym_desc-preproc_bold_postprocessed.nii.gz and be located in a folder like: /proj/mnhallqlab/proc_data/sub-220256/func/ where 'func' is the modality, 'task' is the type, 'ridl' is the task_name, and '_postprocessed' is the suffix.

Value

a data.frame containing all run_nifti and confound_input_file results for subjects in the folder
