Welcome!

This is MRS, a search engine for biological and medical databanks. Use it to search well over a terabyte of indexed text.

Usage

Usage of MRS should be straightforward. Just type some search terms in the search field at the top of the window and hit the Search button. More complex queries can be used as well, see the manual for more information.

New version

MRS-4, the version you're currently using, has the new ability to search for phrases. This means that if you now search for e.g. "retinal degeneration slow" you will get less, but more relevant results.

Tip

If you're using Firefox or Internet Explorer, you can now add MRS to your list of search engines by clicking here.

Open Source

MRS was designed and implemented by Maarten Hekkelman at the CMBI with the help and contributions from many others. It is distributed under a BSD license. You can find the source code for the current version at ftp://ftp.cmbi.ru.nl/pub/software/mrs/

There's a mailinglist for issues related with MRS, to subscribe go to http://lists.berlios.de/mailman/listinfo/mrs-user.

Abstract

The biological data explosion of the 'omics' era requires fast access to many data types in rapidly growing data banks. The MRS software provides the tools to rapidly and reliably download, store, index, and query flat-file databanks. Data stored and indexed by MRS takes considerably less space on disk than the raw data, despite that these raw data are included. The MRS index information is part of the stored data. Therefore, public and private data can be combined by simple concatenation and thus without computational overheads.
