SEQREP1 is a Java application that implements virtual potentials for the representation of DNA sequences. In the current version the main functionalities of the software are

  • Coding DNA sequences into SEQREP codes starting from FASTA files.
  • Training Kohonen self-organizing maps (SOMs) with DNA sequences represented as SEQREP codes, and visualization of the results.
  • Application of trained SOMs to new sequences (mapping of the sequences and their automatic classification).
SEQREP1 can be downloaded as a zip file.

Documentation is included in the zip file and is also available online.

Screenshots are available.
