Informatics FAQ

Frequently Asked Questions related to Informatics.

How do I login to the portal?

Many functions of the portal require users to login to access more detailed information. Much of this information is secured and made only available to the user, collaborative group or EDRN community depending on the EDRN data sharing policies. The EDRN DMCC provides each user a secure username and password. This should be used to login to the portal at by clicking or tapping "Log In" (upper right).

If you do not have your username or password, please contact for assistance.

What are the EDRN data sharing policies?

The data sharing policies of EDRN are set by the EDRN Informatics and Data Sharing Subcommittee. These policies are approved by the EDRN Steering Committee. These policies will be posted shortly. In the meantime, if you have questions, please contact

How do I share my scientific data sets within the EDRN?

The EDRN has developed the EDRN Catalog and Archive Service (eCAS) as a mechanism to allow for distributing data generated during EDRN biomarker studies. This application provides a secure means to share data both wiithin and outside the EDRN research community. At the moment, if you would like to have your data hosted on eCAS, please contact .

The Informatics Center is also developing a laboratory-specific implementation of eCAS, LabCAS, that will be available to EDRN laboratories to help them in processing and sharing data through a set of web-based applications. This is currently being tested as part of a collaboration on proteomics with Vanderbilt University.

eCAS has been supplanted by LabCAS.

What tools exist to help me with study management?

The EDRN Informatics Center is an active REDCap consortium partner and hosts a REDCap implementation on our local server. An initial pilot has been performed with University of Texas at San Antonio. REDCap provides support for managing data capture within research studies using secure web-based software. Tools are provided to allow users to build their own online data collections. The EDRN provides a standard set of Common Data Elements (CDEs) that can be used to structure the data in a standard manner. For more information, please contact

What are the EDRN CDEs?

The EDRN provides a standard set of data elements called Common Data Elements that can be used to structure forms and build systems. These are used in a variety of informatics applications and have been developed with the EDRN since its inception. For more information, search "CDEs" on this site or contact

How do I get access to Biomarkers?

Biomarkers from EDRN studies are captured and cataloged within the EDRN Biomarker Database. They are available by searching "biomarkers" on this site. The biomarkers are curated and initially set to a private state until the information is reviewed by the investigator and the EDRN collaborative group. The content includes the information defined by the EDRN and NCI community.

How do I share my Biomarkers?

If your biomarker information is not captured or is incomplete, feel free to contact Maureen Colbert who can help coordinate capture of the biomarkers with the EDRN biocuration team at Dartmouth Medical School.

How do I find Specimens?

Specimen information is captured and integrated from a variety of sources. This includes real-time information from EDRN databases hosted by different laboratories as well as reference sets. A number of sites have already been integrated into this system. This information can be accessed by searching "Specimens" on this site.

How do I share my Specimens?

If you have specimens that you would like to share, feel free to contact EDRN has a variety of mechanisms that can be used to capture and share specimens.

What protocols are being studied within the EDRN?

The EDRN captures protocols that are being studied by the investigators that are part of the EDRN research community. These can be accessed by searching "Protocols" on this site. These protocols include the team projects that are currently under development.

What if my protocols are missing?

If you have protocols that you would like included, please contact who can help coordinate curation of that information.
