What is Connectome in a Box?
It's free, right?
Unfortunately, no. Researchers are required to pay for the drive as well as shipping and processing costs. The HCP makes no profit from the sales of Connectome data. We have worked to minimize the cost to the research community and will adjust pricing as market rates drop for high capacity drives. Currently, the total cost to investigators for each drive of data is approximately $200, including shipping costs. (Non-US customers can expect to pay more.)
What if I want to "try before I buy"?
We highly recommend interested HCP data users visit ConnectomeDB and download packages of data from one of our pre-selected subject groups.
What formats does Connectome in a Box come in? Can I get it formatted for Mac? Linux?
As of July 2013, we are only shipping drives formatted for Linux (EXT3). However, there are workarounds available for Mac and Windows users. Please see this updated note on drive formats for more information.
When can I expect shipment?
All standard orders will ship within 30 days of their initial order.
This is an internal hard drive? What if I have a laptop?
We anticipate two kinds of users ordering these drives. One will be able to take the drive out of the box and give it to their IT person, who will transfer the data onto their network storage unit and make it broadly available to the investigators at their center.
The other will want to plug it right into whatever computer they use and get at the data directly. For this second class of users, we highly recommend purchasing the HCP Starter Kit, which is a single-drive dataset. An enclosure can be ordered along with Connectome in a Box (again, at cost – and we’ll even load the drive into the enclosure for you!). While there are many alternative options available, many do not work well with high capacity drives so choose carefully.
What happens when future data releases come out?
Each time a new dataset is released, interested users will be able to order the data on a new drive. Drive prices may change from release to release, based on our cost from suppliers.
What happens if a data set I already have is updated?
There are two classes of updates. In July 2013, we completely reprocessed all data, which made data on the original Q1 drives incompatible with newer data. In that instance, we strongly recommended replacing data with new drives. In two instances since then, we have released simple data patches users can apply to their current data to fix issues and replace missing files.
Please note: the data released in the 500 Subjects Release has been newly reprocessed, and should not be mixed with data from previous releases.
Can I "recycle" hard drives with old data on them?
We have canceled the HCP drive recycling program, as of the 500 Subjects Release. This decision was the result of a cost-benefit analysis that factored in the upsurge of drives that we need to manage for each shipment, the impact of maintaining such a program on our internal resources, and the relatively low usage of the program over the past 15 months.
What if I get a bad hard drive? Can I return it?
Prior to shipping, the accuracy and completeness of the data on each drive is digitally verified. However, it’s possible that a drive may become defective after shipping. If your drive stops working within 30 days of receipt, you may ship it back for a replacement at no additional cost. Please contact email@example.com for more information.
How does the HCP create the drives?
The HCP informatics team has assembled a high throughput drive duplicator, referred to by its builders as the “duplicatinator.” It includes 15 hot swappable drive bays and a single mount for a master drive. Each bay is hooked into the replication hardware with a 6 GB/s SAS channel. To increase efficiency, we are now using RSync to duplicate drives. Once the copies are completed, we use a checksum to verify data integrity.

Thank you for your interest in ordering HCP Data. The storefront will be relaunched soon to accept orders for Q3 data, as well as reprocessed data from Q1 and Q2. In the meantime, feel free to download individual packages of data from ConnectomeDB.
Current users: There will be a patch available shortly on ConnectomeDB to update Q1 and Q2 data.
If you would like to receive an update when the storefront is ready for orders, please sign up to our HCP Announce mailing list.
