DNA Sequence Assembler

DNA Sequence Assembler features



The main and most important feature of DNA Baser Sequence Assembler is that it FULLY automates the DNA sequence assembly process.

Just point the progra to the folder where your samples are and the program will do ABSOLUTELLY all steps for you. This is why you will see the word 'automatic' a lot in this page.
Features by date.




Some of the core features are


DNA sequence assemby Automatic cleaning (trimming) of the bad ends of chromatograms

DNA sequence assemby Automatic recognition sequence (vectors, primers) cleaning

DNA sequence assemby Automatic correction of the ambiguous bases in contig. You will never have to edit your contigs!

DNA sequence assemby Automatically save the contig, log and project data to disk.

DNA sequence assemby Automatic primer detection and vector removal.

DNA sequence assemby Automatic batch assembly. Thousand of contigs can be assembled at once

DNA sequence assemby Assemble to reference

DNA sequence assemby Synchronized display between chromatograms and contig, which makes the correction of ambiguous bases much faster and easier.

DNA sequence assemby A rapid navigation between ambiguities/mismatches. Jump to the next mismatch with just one click

DNA sequence assemby Integrated base caller

DNA sequence assemby Chromatogram viewer and editor (ABI and SCF).

DNA sequence assemby Project map

DNA sequence assemby Top accuracy - DNA Sequence Assembler is not using a "partial solution" algorithm like other programs.

DNA sequence assemby Save project (input sequences, contig, user edits, etc) to disk for later inspection/editing. You can later add additional samples to your contig.

DNA sequence assemby Remember base edits made by user!



Embedded biology tools

Other features

DNA sequence assemby Easy to use interface: the user can make a contig with only 3 mouse clicks. Just drag and drop your files, then press the 'Start' button and the contig is done. Details.

DNA sequence assemby BEST price on the market and significant discount when several licenses are ordered. Please see the Prices page for more details

DNA sequence assemby Low resource requirement: it can run even on very old systems. Incredibly small size: The size of the whole package is about 2MB.

DNA sequence assemby 100% safe. DNA Baser will never alter your input chromatogram files (results are saved in separate files). Details.

DNA sequence assemby Auto updating. The program automatically checks and downloads updates from the Internet. Updates are free.

Supported file types

DNA Baser supports all popular DNA file formats: ABI, SCF, SEQ, TXT, FASTA, multiFasta, GBK, multiGbk. For details please see this page.

Minimum system requirements

  • Pentium I
  • 0.1 GB RAM
  • Windows XP or higher
  • 4MB free space
  • Monitor resolution: 1024x768

The program requires only few MB or RAM when assembling small contigs. However, more RAM is needed for larger contigs. Note: the program is not suitable for large meta-genomics projects.
