You are using '__BROWSER__' version '__VERSION__' which is too old for this version of MRS. Please upgrade to e.g.: Firefox 3.5, Microsoft Internet Explorer 9, Opera 9.8 or Chrome 10.0.

You should enable DOM storage in Firefox, you can do so in about:config, the key you need to edit is dom.storage.enable and it should be 'true'.

## 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.

## New version 6

MRS 6, or M6, is a complete rewrite of MRS.

## Feedback

If you have suggestions for improvement, please mail to M.L. Hekkelman. Or even better, use the mailinglist to post and discuss them. You can find the mailinglist at

## SOAP access

This MRS server can be accessed using SOAP, the wsdl's are located at:

- ${wsdl['mrsws_search']}
- ${wsdl['mrsws_blast']}
- ${wsdl['mrsws_align']}

## Open Source

MRS was designed and implemented by Maarten Hekkelman at the CMBI with the help and contributions from many others. Version 6 is distributed under a Boost license. You can find the source code for this version at

## 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.

When using this server or the software, please refer to:
