Aspera provides a fast method of downloading data. To use the Aspera service you need to download the Aspera connect software. This provides a bulk download client called ascp.
Our aspera browser interace no longer works. If you wish to download files using a web interface we recommend using the Globus interface we present. If you are previously relied on the aspera web interface and wish to discuss the matter please email us at email@example.com to discuss your options.
For the command line tool ascp, for versions 3.3.3 and newer, you need to use a command line like:
ascp -i bin/aspera/etc/asperaweb_id_dsa.openssh -Tr -Q -l 100M -L- firstname.lastname@example.org:vol1/ftp/release/20100804/ALL.2of4intersection.20100804.genotypes.vcf.gz ./
For versions 3.3.2 and older, you need to use a command line like:
ascp -i bin/aspera/etc/asperaweb_id_dsa.putty -Tr -Q -l 100M -L- email@example.com:vol1/ftp/release/20100804/ALL.2of4intersection.20100804.genotypes.vcf.gz ./
Note, the only change between these commands is that for newer versions of ascp asperaweb_id_dsa.openssh replaces asperaweb_id_dsa.putty. This change is noted by Aspera here. You can check the version of ascp you have using:
The argument to -i may also be different depending on the location of the default key file. The command should not ask you for a password. All the IGSR data is accessible without a password but you do need to give ascp the ssh key to complete the command.
For the above commands to work with your network’s firewall you need to open ports 22/tcp (outgoing) and 33001/udp (both incoming and outgoing) to the following EBI IPs:
If the firewall has UDP flood protection, it must be turned off for port 33001.
