Hi, I am not very familiar with docker. I have pulled down the image, but I don't know how to copy the data out of the image. (Such as :"DTC_pkd_inchikey_to_smiles" in data folder in docker) I tried "docker cp docker.synapse.org/syn18519352/qed-sub2:9686285:/data/DTC_pkd_inchikey_to_smiles [another path]", but it didn't work. What should I do ? Thank you:)
