greporiter Function Get the positions of replication origin and terminus Description greporiter returns the positions of replication origin and terminus in bacterial genomes by several means. 1. Use of databases By default, grep_ori_ter tries to retrieve the position of replication origin in DoriC Gao and Zhang (2007) database, and the position of replication terminus from the supplemental data provided in Kono et al. (2011). If the position of origin cannot be found in the database, but "rep_origin" feature is available, center position within this feature is used for origin. 2. Oriloc Using -orilocoption, you can predict the replication origin and terminus using the popular Oriloc program developed by Lobry et al. available as part of the SeqinR package Frank and Lobry (2000). 3. Use GC skew shift-point If the positions of origin or terminus cannot be found in the databases, grep_ori_ter automatically calls find_ori_ter() method to predict the positions using GC skew shift-points at one-base-pair resolution. G-language SOAP service is provided by the Institute for Advanced Biosciences, Keio University.
