Hi Yaro, We were unable to find an open source alternative to Aspera that matches its performance and feature set. I do want to emphasize that the Aspera client software is free to end users, so while the Aspera infrastructure is commercial (and costly), HCP users will NOT incur any cost. HCP data are also accessible over http using the XNAT REST API, but your performance will suffer considerably compared to aspera (ie, I would not recommend it for large batches of data).
There are a couple of additional data access methods that we'll be implementing down the road. Working with the INCF, we'll be making the data accessible over INCF Dataspace. We will also be putting the packages up on the Amazon cloud. Kevin will respond to your second question. -Dan On 8/20/13 10:11 AM, "Yaroslav Halchenko" <site-humanconnectome....@onerussian.com> wrote: >Dear HCP Gurus, > >Aspera client seems to perform really well to utilize the available >bandwidth, but it is a closed source proprietary software (although >happily using open source libraries such as Qt, which it can do). >I wonder if there is any other alternative method to access data, >possibly through a less efficient but open protocol (http/rsync/...)? > >Is it possible to use aspera's cmdline client (ascp) directly >from the command line without requiring it being spawn up by >asperaconnect.bin web-browser plugin? if "yes" -- could someone point >me to any HOWTO/etc outlining the procedure for authentication using HCP >credentials? > >Thank you in advance for the answers! >-- >Yaroslav O.
