I'm trying to download the 1000 Genomes (phase 3) through FTP, but it's taking ages. I saw the documentation about using Aspera (fasp protocol), but the instructions don't work: ERR [ascp] SSH authentication failed. Eg: 

ascp -i /home/ibmuser/.aspera/connect/etc/asperaweb_id_dsa.putty -Tr -Q -l 100M \
     -P33001 -L- [email protected]:vol1/ftp/release/20130502/ALL.chr1.phase3_shapeit2_mvncall_integrated_v5a.20130502.genotypes.vcf.gz.tbi ./

Via Aspera Desktop client I got: SSH_MSG_DISCONNECT: 2 Too many authentication failures

Thanks!

You are using the command for older versions. In the page you link to, they give two commands, one for the newer and one for the older versions of aspera. You are using the one for the older. The only difference is the keyfile, but what you want is:

ascp -i /home/ibmuser/.aspera/connect/etc/asperaweb_id_dsa.openssh -Tr -Q -l 100M \
 -P33001 -L- [email protected]:vol1/ftp/release/20130502/ALL.chr1.phase3_shapeit2_mvncall_integrated_v5a.20130502.genotypes.vcf.gz.tbi ./

At least, I just tried this a second ago with the aspera bundle I downloaded today and that's the command that worked: asperaweb_id_dsa.openssh and not asperaweb_id_dsa.putty.

  • $\begingroup$ @BrunoAmbrozio nice! But note that you forgot the sex chromosomes. And also the various alt ones if any are present. $\endgroup$
