Thank you for your interest in the TGI databases.

We are very proud of this project, the work that we have done, and the impact thiat it has had on the community. The TGI databases have been supported by various combinations of programs at NIH, DOE, and NSFsince 1998, the papers describing it have been cited more than 2000 times, and the site still receives more than 7,000,000 million hits each year.

The funding for this project ended in 2010 and while we continued to maintain the website, both the hardware and software supporting it have begun to fail. Effective July 15, 2014, we have suspended operation of the TGI as we lack the funds to maintain it properly.

The software tools that enabled the TGI are still available through the DFCI Gene Indices Software Tools ( page. The entire data sets, including the raw, trimmed sequences, Tensus Consensus (TC) sequences, and other data are available by FTP at

It has been a pleasure serving you and hope that you have found our resources to be of use.
