"Sharing" is caring
"Sharing" is caring
al But what if you don't care? Or don't want to be altruistic?
Let's call it "publishing" instead
Reasons that data sharing publication is important
Based on Poline et al. (2012)
Accelerate progress in understanding the brain
Other fields have already demonstrated the benefits: Astronomy, Genomics are examples
Improve the quality of publications, and of the data
Reduce the cost of research, and increase ROI
Reproducibility

For all these reasons - funding agencies/journals are going to increasingly require that you do it!
A few more “selfish” benefits
Get cited more: The “data sharing advantage”: ~10% more citations when data is shared (all else being equal).This is really just a way of saying that the research is better and has more impact when the data is available.
Similar effects when software is shared - a topic for a different day…
For the time being, people still think you’re somehow being altruistic...
OK - sign me up! How do I do it?

Make sure your IRB approval and consent forms include data "sharing"
Open brain consent makes it easy
Use the Brain Imaging Data Structure to structure your data even before you analyze it:
- A common exchange format that lives in your file-system.
- Will facilitate data-sharing in different databases.
- Will facilitate development of common analysis tools.
Use the automated validator to make sure your format is compliant
If you create a unique dataset:
Consider publishing a data paper!
