datalad create-test-dataset
Synopsis
datalad create-test-dataset [-h] [--spec SPEC] [--seed SEED] [--nfiles NFILES] [--version] path
Description
Create test (meta-)dataset.
Options
path
path/name where to create (if specified, must not exist). Constraints: value must be a string or value must be NONE
-h, --help, --help-np
show this help message. –help-np forcefully disables the use of a pager for displaying the help message
--spec SPEC
spec for hierarchy. Each level is separated by / and has the form [d]min[-max][+Nf]. min-max defines how many (random from min to max) sub-datasets to generate at that level (min can be omitted to assume 0). Prefix d makes entries plain directories instead of subdatasets (e.g. d3 creates 3 dirs with files). Suffix +Nf creates N tracked files per entry at that level (overrides –nfiles for that level). Examples:: 1-3/-2 1–3 subdatasets at L1, up to 2 at L2 2+100f/-2 2 subs at L1 each with 100 files, up to 2 at L2 10/d5+50f 10 subs, each containing 5 plain dirs with 50 files. Constraints: value must be a string or value must be NONE
--seed SEED
seed for rng. Constraints: value must be convertible to type ‘int’ or value must be NONE
--nfiles NFILES
number of files to create in each dataset (default 1). Per-level +Nf suffix in spec overrides this. Constraints: value must be convertible to type ‘int’ or value must be NONE
--version
show the module and its version which provides the command
