I'd like to download the following SRA files:
using aspera connect in our university linux cluster but when I try ascp'ing it asks me for a password, do you know if there is a guest password or I should write to the sra email sra@ncbi.nlm.nih.gov.
Also is there a way to recursively download all the files directly? I was ascp'ing them one by one, would the following command work?
IBM Aspera Connect is a free, install-on-demand application that plugs in to your Web browser to facilitate high-speed downloads with an IBM Aspera transfer server. It uses IBM Aspera's patented FASP transfer technology to achieve speeds that can be hundreds of times faster than FTP/HTTP.
- The latest version of Aspera Connect is 3.9 on Mac Informer. It is a perfect match for Cloud Services in the Productivity category. The app is developed by IBM Corp.
- Click Install Now or Download Aspera Connect on the page. If it is a newer Connect Server, clicking the Install Now triggers the auto installation. When finished, refresh the page and the Aspera Connect should be installed. If it is an older Connect Server, click Download Aspera Connect to go to the Aspera Connect download.
- Unblocking the Aspera plug-in. When globaledit does not recognize aspera, your uploads and downloads may not initiate, a pop-up window may not occur, or the upload dialogue box will display this message at the bottom: Chrome. NOTE: Chrome Plugins are no longer support as of Chrome version 57.
I looked at the http://www.ncbi.nlm.nih.gov/books/NBK47527/pdf/Aspera_Transfer_Gui.pdf but it did not explicity say anything about requiring a password.
Please let me know if anyone has some experience with using Aspera to download GEO data.
Thanks!
