It has been shown that Phred's error probabilities are very accurate - if Phred assigns a quality score of 40 to a base, the chances that this base is called incorrectly are indeed just 1 in 10, see Ewing et al. This high accuracy has been observed for sequences generated at different laboratories, each using a different combination of sequencing enzymes, fluorescent dyes, and gel run conditions Richterich , Genome Research; The high accuracy of Phred quality scores make them an ideal tool to assess the quality of sequences.

The most commonly used method is to count the bases with a quality score of 20 and above sometimes called 'high quality bases' ; the resulting number is often called the 'Phred20 score'. By looking at individual sequences, failed reactions or low-quality reads can easily be identified. When looking at collections of sequences, the effect of different sequencing methods on sequence quality can be directly measured. This allows straighforward quality control in sequencing projects, and can give easily available measures to optimize sequencing operations.

Support for Phred quality scores is fully integrated into CodonCode Aligner. Aligner enables you to run Phred on sequence traces by simply selecting you sequences and choosing 'Call Bases' from a menu. CodonCode Aligner can show Phred quality scores in a number of different ways: by shading the background behind bases according to quality, in a separate 'quality view', or as a summary of 'Phred20' scores in the project view.

CodonCode Aligner can also use quality scores during sequence assembly to build the consensus sequence, automatically selecting the consensus base that is most likely to be correct. Such quality-based consensus sequences can be much more accurate than majority-based sequences, especially in areas of low coverage.

Free demo versions of CodonCode Aligner are available for download. Cell Counter is a freeware tool that will help you to manually count the cells shown on computer screen by displaying a transparent or semi-transparent grid over your image. NextGen bioinformatics tools. Sequence Dereplicator is a graphic interface tool that allows you to dereplicate your Fasta sequences via sequence clustering. NCBI suite. Now you can harness the power and accuracy of DNA Baser at a new level by performing custom sequence assembly from your very own scripts.

In situ hybridization of genes and mRNA is most often based on polynucleotide probes. We recently developed a concept and software PolyPro for rational design of polynucleotide probe mixes to identify particular genes in defined taxa. Convertrix is a molecular biology command line tool for converting between several popular DNA sample formats.

It can automatically trim the untrusted regions low quality bases at the end of samples.
