gldabias Function Calculate strand bias of bacterial genome using linear discriminant Description gldabias calculates strand bias of bacterial genome using linear discriminant analysis (LDA), as proposed in Reference 1. The basic idea is to use composition data of genes to train and predict the strand of genes residing either on the leading or the lagging strand. For computational efficiency, this method trans and predicts the strands at putative replication origin as reported by the rep_ori_ter() method. This usually results in maximum predictability of LDA within bacterial genomes. Data to use for LDA can be chosen from "base", "codonbase", "codon", and "amino", with -variable option. G-language SOAP service is provided by the Institute for Advanced Biosciences, Keio University.
