The query for protein labeled images will be made available shortly.

Current Status
Version 2.0, August 20, 2004
Please check back for release notes.

1. The database is now using Oracle 9i.

2. Protein localization query can be performed on Optical Section and Electron Tomography data sets.

3. Advanced query of general description information (e.g., project, anatomical detail, subject) can be performed on all the available datasets.

4. Advanced query of quantitative measurement (e.g., neuron summary, cell body, axon, dendrite, and spine) analyzed by Neurolucida 4.35C can be performed on optical section datasets.

5. Available datasets for download: ACC1, ALXP, e1cb4a5, e1cb4a1, e17hpc1a, e1cb3a1, e13hpc1c, pccor10, osaka3, ACC1_2ma, e4cb2a2, pccor10_dc, e4cb3a1, e1cb3a1_p, e1cb10a2, e1cb10a3, 71202tjd.

6. JViewer3.0 can now read and display Synu Viewdata and polygonmesh, triangle mesh, and sphere geometry files.

Version 1.1, June 2002

1. 10/15/2003: JViewer has been updated to give surface area measurement information for Synu data files.

2. 9/17/2003: CCDB was migrated from development to production level servers.

3. 7/25/2003: Registered Users can submit evaluation and view feedback on reconstruction images.

4. 7/25/2003: Mapped the CCDB to the UMLS/Bonfire ontologies.

5. 6/5/2003: Neuronal branching Query to search and compare neuronal branching pattern is made available.

6. 5/7/2003: The CCDB is now tracking access and download activities. This data is used solely for the purpose of assembling statistics on usage of the CCDB for annual reports.

7. 5/5/2003: Quick download of images and image analysis from SRB is now available.

8. 4/15/2003: A link to cell data in the Sense Lab database has been added to the query brief results page.

9. The registration and log in features are now active.

10. 3D data sets from confocal microscopy are now available for viewing.

11. Neuronal branching structures generated by Neurolucida from confocal datasets are now available for viewing and downloading.

12. Limited 3D data sets from Electron Tomography are now available for viewing.

13. A Neurolucida data viewer (JViewer) is now working and integrated into the CCDB.
