fcp_list_files(prefix = "", delimiter = NULL, query = NULL, ...)

openneuro_list_files(prefix = "", delimiter = NULL, query = NULL, ...)

hcp_list_dirs(prefix = "HCP/", ...)

fcp_list_dirs(prefix = "data/Projects/", ...)

openneuro_list_dirs(prefix = NULL, ...)

Arguments

prefix	directory folder to list files. If "", then it will be the root path
delimiter	Delimiter to list files. For example ".mat", for ".mat"
query	Additional query arguments
...	additional arguments passed to get_hcp_file

if (have_aws_key()){
x = hcp_list_files(prefix = "HCP/100307/unprocessed/3T/Diffusion",
   delimiter="bval")
t1_niis = hcp_list_files(prefix ="HCP/100307/T1w",
delimiter = ".nii.gz")
all_dirs = hcp_list_dirs("HCP/")
