General Order Information
There is no cost to receive any NDACAN dataset. NDACAN prepares datasets for distribution on MS Windows workstations and include digital documentation and installation instructions. Documentation for most datasets consists of a users guide, codebook, original instruments, and references to relevant publications. Each dataset is distributed in one compressed .zip package which contains the data files. You can open .zip packages with MS Windows' built-in extraction (open the .zip package and choose File > Extract All). You can also use a free utility called 7Zip, or other .zip package software. After you have extracted the contents of a .zip package to your hard drive, open the "Readme" (or equivalent) file for information about the data files.
File Delivery
NDACAN uses Box.com to deliver datasets. NDACAN will create a folder with your dataset(s) on Box.com and add your e-mail address (as you provided it in the Terms of Use Agreement) as a collaborator to the folder. You will then receive an e-mailed invitation from Box.com to login and download the data. Make sure that your junk mail filters allow you to get mail from Box.com. If you don't already have a free box.com account that is connected to the e-mail address you provided, you must create a free box.com account with that e-mail address and then log in to Box.com with that e-mail address to download your files. The name of Box.com's free account service is the Individual Plan

Your file(s) for download will expire in only 10 calendar days from when you receive the download invitation from Box.com: please download immediately.
