[Pattern recognition in the computer analysis of nucleotide sequences].

We have used an algorithm from the pattern recognition theory "generalized portrait" to find a distinguishing vector for Escherichia coli promoters. We have made an attempt to solve closely linked problems for choosing significant signs of that signal, multiple alignment and for calculation of the recognition vector (matrix). The promoters with known strength have been ranged with this vector. The analysis of the occurrence of predicted promoters has been carried out. The promoters search program for IBM-compatible computers is available from the authors.
