What's new?

SIMAP will leave BOINC by end of 2014 SIMAP is currently moving towards new algorithms for similarity calculations and scoring. After extensive tests and evaluations during the last months it turned out that the best way to continue SIMAP will be to use dedicated local hardware in our institute. SIMAP will therefore use BOINC only to maintain the current SIMAP database until the end of 2014. BOINC clients for the new SIMAP database will not be released and there will be no workunits for SIMAP after 2014. After 10 very successful years of SIMAP within BOINC this decision was not an easy one for us. However, we thank all users for their support in the past and in the upcoming last period until the end of the year.

What is SIMAP?

Protein structure

Proteins are the main functional units of all living organisms. If we want to understand human life, aging and disease, we need to study proteins. If we want to harvest compounds and energy from microorganisms, we need to study proteins. If we want to relate global biogeochemical cycles to changing climate conditions, we ... yes - need to study proteins. However, this is no simple task. Many million protein sequences (the arrangement of their building-blocks) have been characterized so far. Many thousand new ones are discovered every day. The similarities among all these protein sequences are crucial for protein research. They help us studying the structure and function of proteins, and their biological roles. SIMAP facilitates protein research by providing pre-calculated protein similarities and protein domains. Read more...

What do you do in BOINCSIMAP?

protein alignment

SIMAP contains about all currently published protein sequences and is continuously updated. In BOINCSIMAP, we calculate the similarities of newly imported proteins. Thereby we keep the SIMAP database up-to-date. Protein similarities are computed using the FASTA algorithm which provides optimal speed and higher sensitivity compared to the popular BLAST.

Why do it?

Eukaryotic cell

The SIMAP database is an important bioinformatic resource that is used by scientists from all over the world. All data from SIMAP are freely available. Individual researchers use the SIMAP database via the public Web portal, e.g. to investigate the evolution and function of individual proteins. Furthermore, many bioinformatics projects access SIMAP directly via the public Webservice or large-scale download facilities. Your support for BOINCSIMAP keeps the SIMAP database running.

How do it?


BOINC lets you contribute unused computing power of your computer or mobile device to research projects. You may contribute to a single project (like BOINCSIMAP), or to any combination of them. It's easy to participate in a BOINC project: download and install BOINC. You will be asked to select a project and enter your email address and a password. That's it! Read more...
