## Overview
-DUMA is an IBM Aspera deployment at the LCSB-University of Luxembourg. DUMA supports end-to-end encrypted data transfer and can handle high data volumes e.g. several tera bytes.

+## Obtaining a AsperaWEB access link
-You need an **access link** to use DUMA. An access link is a temporary, password-protected space, much like a drop box, on LCSB's DUMA server. In order to obtain an access link, you should contact your research collaborator at the LCSB-University of Luxembourg. Once created, you will receive your **access link** and associated **password** (link) by e-mail.

An access link can be reached via standard web browsers. Data can be transferred to/from an access link in two ways:
-* Through the web browser by visiting the link, which is our recommended way of data transfer, described in this [section of the guide](#DUMA_WEB)
-* Through the use of a command line tool. If your data sits in an environment, where you can not launch a web browser, then you may use use a command line client tool to reach an access link. This process is described in this [section of this guide](#DUMA_CLI).

-## Accessing DUMA via Command-Line Tool
-In the following steps we describe instructions on how to use DUMA web interface.
-
-1. **Install the aspera command line client.** The _ascp_ tool, which can be found [here](https://downloads.asperasoft.com/en/downloads/62) as instructed.
-
-1. **Obtain tokens.** You will need **tokens** while using _ascp_. You will need a **download token** for download and a separate **upload token** for upload. Your tokens can be viewed by clicking the **Help** icon on your access link (see below).<br/>
-  <br/><br/><br/>
- 
-
-1. **Obtain encryption passphrase.** You should receive corresponding passphrase from repository administrator.
-
-1. **Obtain SSH key.** You will also need an **SSH private key** to authenticate. This is the Aspera key that comes with the Aspera Connect installation named `asperaweb_id_dsa.openssh`. Below are locations where the ssh_key can be found:
-
-
- * On MAC
- * Local installation of Aspera connect:
- * `/Users/username/Applications/Aspera Connect.app/Contents/Resources/asperaweb_id_dsa.openssh`
- * System wide installation of Connect:
- * `/Applications/Aspera Connect.app/Contents/Resources/asperaweb_id_dsa.openssh`
-
- * On WINDOWS
- * Local installation of Aspera connect:
- * `C:\\Users\username\AppData\Local\Programs\Aspera\Aspera Connect\etc\asperaweb_id_dsa.openssh`
- * System wide installation of Connect:
- * `C:\\Program Files (x86)\Aspera\Aspera Connect\etc\asperaweb_id_dsa.openssh`
-
- * On LINUX
- * Local installation of Aspera connect:
- * `/home/username/.aspera/connect/etc/asperaweb_id_dsa.openssh`
- * System wide installation of Connect:
- * `/opt/aspera/etc/asperaweb_id_dsa.openssh`
-
-1. **Set necessary environment variables**. `KEY` and `TOKEN` environment variables should be set as follows. If you do not have any of the tokens use `None` as the value.
-
- * `KEY=<path to the ssh key>`
- * `DTOKEN=<<<<YOUR DOWNLOAD TOKEN>>>>>>`
- * `UTOKEN=<<<<YOUR UPLOAD TOKEN>>>>>>`
- * `export ASPERA_SCP_FILEPASS=<<<<<YOUR ENCRYPTION PASSPHRASE>>>>>`
+<a name="ASPERAWEB_CLI"></a>
+## Accessing AsperaWEB via Command-Line Tool
-1. **Run the relevant _ascp_ commands**.
+Go to the help section of your access link
- * Upload:
- * To upload all *png* files to the root of the share:
- * `ascp -d -i $KEY -P 33001 --file-crypt=encrypt -W $UTOKEN *.png app_duma_public_read@aspera.lcsb.uni.lu:/`
- * To upload *document.txt* to a subfolder:
- * `ascp -d -i $KEY -P 33001 --file-crypt=encrypt -W $UTOKEN document.txt app_duma_public_read@aspera.lcsb.uni.lu:/subfolder`
- * Download:
- * To download *subfolder* and all it's content to the current directory:
- * `ascp -d -i $KEY -P 33001 --file-crypt=decrypt -W $DTOKEN app_duma_public_read@aspera.lcsb.uni.lu:subfolder`
+<br/>  <br/><br/><br/>
+And follow the steps in the **Using the command line** section.
