Download using Aspera

When downloading large volumes of data, the Aspera protocol can be useful. You will need to download the Aspera ascp command line interface. Please select the correct operating system. The ascp command line client is present in the bin folder in the installation directory. Your command for download should be like this:

ascp -P33001 -i <key> bsaspera@fasp-beta.ebi.ac.uk:<files to download> <download location on your machine>

where:

• -P33001 and bsaspera@fasp-beta.ebi.ac.uk define the port, user and server for the Aspera connection
• <key> is the public key for the Aspera connection which has the value <aspera cli installation directory>/etc/asperaweb_id_dsa.openssh for Linux/MacOS and <aspera cli installation directory>\etc\asperaweb_id_dsa.openssh for Windows
• <files to download> might be all files for a certain study, as explained above. Please note that Aspera paths do not need to have pub as the root folder

For example, here’s the command line to download the file aeipf_denoised_reads.fna from submission S-BSST12 to the directory C:\Temp on Windows:

"C:\cli\bin\ascp.exe" -P33001 -i "C:\cli\etc\asperaweb_id_dsa.openssh" bsaspera@fasp-beta.ebi.ac.uk:/S-BSST/012/S-BSST12/Files/aeipf_denoised_reads.fna C:\Temp\
