Data Sharing Policy: The mission of the CCDB is to promote data sharing among scientists interested in cellular and subcellular anatomy and in developing computer algorithms for 3D reconstruction and modeling of such data. Data sets may be viewed or shared at the discretion of the author of the data. In some cases, the data may be freely viewed and Downloaded without contacting the original author, while in other cases, permission of the author may have to be obtained prior to receiving data. In either case, failure to cite or give credit to the original authors who collected these data in subsequent published articles or presentations is on par with plagiarism, is unacceptable, and unprofessional. Although the CCDB is not in a position to police every intended use of these data, we trust that the scientific community will ensure that this does not happen. However, we do insist that researchers re-analyzing these published data reference the original published article and the CCDB. An example of an appropriate acknowledgement is provided in the usage terms agreed to upon data download and is also included below

The CCDB schema is owned by the CCDB. Individual data and data sets remain the property of the principal investigator who contributed it. Any question as to proper use of this data set should be directed to the principal investigator and the CCDB.

Depositing Data to the CCDB: The CCDB will accept data from outside users. Policies for deposition of outside data are still being developed, but it is expected that users will deposit data in accordance with the mission of the CCDB to make 3D cellular and subcellular data available to the greater scientific community. Thus, any data deposited must have sufficient descriptive data that is interpretable by an independent user and as far as possible, original imaging data should be included.

The data provided by the CCDB is freely distributed. This data is distributed in the hope that it will be useful but without any warranty. This data is provided by CCDB “as is” and any express or implied warranties, including, but not limited to, the implied warranties of merchantability, fitness for a particular purpose, or non-infringement, are disclaimed. In no event shall the CCDB be liable for any direct, indirect, incidental, special, exemplary, or consequential damages (including, but not limited to, procurement of substitute goods or services; loss of use, data, or profits; or business interruption) however caused and on any theory of liability, whether in contract, strict liability, or tort (including negligence or otherwise) arising in any way out of the use of this data, even if advised of the possibility of such damage.


Data used from the CCDB should be appropriately referenced, including both the author of the data and the CCDB. If the data were from a published study, the reference is included in the database record. The following reference should be cited for the CCDB:

Martone, M. E., Gupta, A., Wong, M., Qian, X., Sosinsky, G., Ludaescher, B., and Ellisman, M. H. A cell centered database for electron tomographic data. J. Struct. Biology 138: 145-155, 2002.

In addition, the support for the Cell Centered Database should be included in the acknolwedgement section of any publication:

The Cell Centered Database is supported by NIH grants from NCRR RR04050, RR RR08605 and the Human Brain Project DA016602 from the National Institute on Drug Abuse, the National Institute of Biomedical Imaging and Bioengineering and the National Institute of Mental Health, and NSF grants supporting the National Partnership for Advanced Computational Infrastructure NSF-ASC 97-5249 and MCB-9728338.
