Abstract

TWINSCAN is a gene-prediction system that combines the methods of ab initio predictors like GENSCAN with information derived from genome comparison. This unit describes the use of TWINSCAN to identify gene structures in eukaryotic genomic sequences. Protocols for using TWINSCAN through its Web interface and from the command line in a Linux environment are provided. Detailed discussion about the appropriate parameter settings, input sequence processing, and choice of genome for comparison are included.

Keywords:

  • TWINSCAN;
