Is there a way to download only part of a datalad dataset?

1

For example:
datalad install -g ///adhd200/RawData/Brown downloads the entire dataset.

But lets say I only want:
RawData / Brown / 0026001 / session_1 / anat_1
Is there a way to achieve this?

I also posted this on stack overflow: https://stackoverflow.com/questions/61598527/is-there-a-way-to-download-only-part-of-a-datalad-dataset

Yes, but you have to use two commands. Here is the complete code (confirmed to work with the current DataLad release 0.12):

datalad clone ///adhd200/RawData/Brown
datalad -C Brown get 0026001/session_1/anat_1

Instead of install --get-data, first clone the dataset (you can also keep using install, but strip the -g option). This will obtain the “empty” dataset only (which is fast and lean). Then follow it up with a get for the files you are interested in. The -C changes the working directory to the root of the Brown dataset – just like Git’s -C option.
