Heather A. Piwowar has written an article entitled “Who Shares? Who Doesn’t? Factors Associated with Openly Archiving Raw Research Data”. By means of a simple full-text query she tried to identify studies in which gene expression microarray datasets were generated.
11,603 data collection studies were included.
Piwowar found that 25% of studies that performed gene expression microarray experiments have deposited their raw research data in a primary public repository. She suggests that perhaps 45% of recent gene expression studies have made their data available somewhere on the internet.
This can be interpreted as a slow, but steady trend toward Open Access to research data.
But there are some in the research community who sheer out of this course. “Authors of studies on cancer and human subjects were least likely to make their datasets available.”
Heather A. Piwowar calls this “disheartening” to discover.
Why not call it miserable?
