Your sign-in request has to be accepted by a moderator. Once your request has been accepted, you can enter the HDNGateway interface. Otherwise, if you have received via e-mail an invitation to the HDN-Lab and you have accepted it, you do not have to wait for acceptance by the moderator.
On the right-hand side of the interface, you will find the logo of the HDN-Lab VRE (Virtual Research Environment). Please, click on it to access the HDN-Lab VRE.
In the HDN-Lab interface, click on the image-folder-like icon of the menu at the top-left of the page in order to access the workspace.
In the panel on the left-hand side, click on the HDN-Lab folder and then on the Repository folder. You can upload your files here, using the Upload button of the folder menu or through drag-and-drop from your computer.
