Intuitive and Accurate Sequence Assembly

CodonCode Aligner supports flexible workflows for assembling DNA sequences efficiently — with advanced features not found in other tools. Examples include direct comparison of contigs from different clones and trace sharpening to improve readability in low-quality regions.

Sanger Sequencing: Assemble and Edit with Speed and Precision

Sanger sequence assembly view

Assemble projects ranging from a few reads to thousands of reads quickly and accurately, and with minimal setup. CodonCode Aligner offers a number of unique features to streamline the assembly process, for example the ability to group samples by name for assembly, producing separate contigs for each sample group.
When manual editing is required, CodonCode Aligner makes editing fast and intuitive, with additional automated tools to resolve base disagreements, clean up assemblies, and improve overall sequence quality.

Sequence Comparison: Visualize Differences and Align Sequences with Ease

Compare sequences to references or to each other using flexible alignment options and purpose-built tools. CodonCode Aligner presents results in views and tables designed to support interpretation and follow-up analysis.

Fast, Flexible Sequence Alignment and Comparison

Multi sequence alignment with ClustalO showing Sanger sequence trace

Perform pairwise or multiple sequence alignments using integrated tools like Clustal Omega, MUSCLE, Bowtie2, and translation-based methods, or use Aligner’s built-in algorithms for rapid reference-based comparisons.
