GCSI quantifies the degree of GC Skew. In other words, this index - represents the degree of strand-specific mutational bias in bacterial - genomes, caused by replicational selection. - GCSI is calculated by the following formula: - - GCSI = sqrt((SA/6000) * (dist/600)) - - where SA is the spectral amplitude of Fourier power spectrum at 1Hz, - and dist is the normalized Euclidean distance between the vertices of - cumulative GC skew. - - GCSI ranges from 0 (no observable skew) to 1 (strong skew), and Archaeal - genomes that have multiple replication origins and therefore have no - observable skew mostly have GCSI below 0.05. Escherichia coli genome has - values around 0.10. - - Version 1 of GCSI required fixed number of windows (4096), but the new GCSI - version 2 (also known as generalized GCSI: gGCSI) is invariant of the number - of windows. GCSI version 1 is calculated as an arithmetic mean (as opposed - to the geometric mean of gGCSI) of SR (spectral ratio, the signal-to-noise - ratio of 1Hz power spectrum) and dist. - - G-language SOAP service is provided by the - Institute for Advanced Biosciences, Keio University. - The original web service is located at the following URL: - - http://www.g-language.org/wiki/soap - - WSDL(RPC/Encoded) file is located at: - - http://soap.g-language.org/g-language.wsdl - - Documentation on G-language Genome Analysis Environment methods are - provided at the Document Center - - http://ws.g-language.org/gdoc/ - -Usage - -Here is a sample session with ggcsi - -% ggcsi refseqn:NC_000913 -GC Skew Index: an index for strand-specific mutational bias -Program compseq output file [nc_000913.ggcsi]: - - Go to the input files for this example - Go to the output files for this example - -Command line arguments - - Standard (Mandatory) qualifiers: - [-sequence] seqall Nucleotide sequence(s) filename and optional - format, or reference (input USA) - [-outfile] outfile [*.ggcsi] Program compseq output file - - Additional (Optional) qualifiers: (none) - Advanced (Unprompted) qualifiers: - -gcsi selection [2] GCSI version to use - -window integer [4096] Number of windows.
