Abstract: Provided is a method of assembling a genome, including: determining the reference appearance rates, that are the appearance rates of all n-base motifs in the nucleotide sequence of a reference genome, in which the n-base motif is a nucleotide sequence containing n bases; and the sample appearance rates, that are the appearance rates of all the n-base motifs in the nucleotide sequences of DNA fragments, calculating the deviations of the sample appearance rates from the reference appearance rates for all the n-base motifs; selecting a predetermined number of n-base motifs having smallest deviations and sample appearance rates of not less than a predetermined value; converting the nucleotide sequences of the DNA fragments into DNA fragments in genome map format using the predetermined number of n-base motifs selected; and assembling the DNA fragments converted in genome map format to generate assemble contigs derived from the DNA in the sample.

Abstract: A system in which researchers can freely and effectively use worldwide bioinformatics analysis programs available on the Internet is provided. When a bioinformatics analysis program available on the Internet is used by a user computer, a broker program is used. The broker program has a function of absorbing differences in input/output format between analysis programs, and each analysis program is provided with the broker program. A broker program-providing server stores various broker programs provided by users and makes them available to the public. When the user uses bioinformatics analysis programs available on the Internet, the user can use broker programs that are made available by the broker program-providing server and that are created by other users.

Abstract: Necessary information can be easily extracted from a plurality of databases 11 in which biological substance information is stored. Data is downloaded from the plurality of databases. From the downloaded data is extracted information indicating links between two databases, a detailed description of each data, and sequence data for homology search, which together constitute an index. The thus extracted index 15 is distributed to a user facility, where a user 18 conducts a search using the distributed index.
