View Features in Multiple Sequence Alignments

Features in the input sequences are carried through to the alignment, allowing you to visualize aligned regions in context.

View and Export History in Text Format

History view now supports both the traditional Maps format and a new Text format.

RNA Sequence Files

The new .rna file format allows you to create, view, and edit RNA sequences.

New ‘All Files’ Area in Collections

Organize all of your DNA, RNA, and protein files within a single list or folder tree in a Collection, and add new folders across the different areas in a single step.

View Sequences in Blocks of 3 or 10 Residues

New layout options allow sequences to be displayed with gaps every 3rd or 10th base.

Fill In Annealed Oligos

Overlap two oligos, and then convert to double-stranded DNA in a single step by filling in the overhangs.

Primers with 3' Overhangs

A DNA sequence can now be annotated with primers that anneal at the 5’ end but not the 3’ end.

Wrapped View for Chromatogram Files

Display and print a chromatogram in multi-line format to view the trace more efficiently.

Improved Geneious Format Conversion

Individual .geneious protein and nucleotide sequences, including features, primers, and alignments, are now imported more reliably with richer information.

SnapGene 5.2

Released 10/2020 | SnapGene 5.2 Detailed Release Notes

SnapGene 5.2 provides visualization and performance enhancements. Highlights include GC content visualization, support for finding similar DNA sequences, simulation of supercoiled DNA migration in agarose gels, support for ssDNA sequences, and Sequencher file import.

SnapGene 5.2 Feature Overview

Watch for an overview of the new features in SnapGene 5.2

GC Content Display

A GC content color or line plot can now be displayed in Map view, and bases can be colored by GC or AT in Sequence view.

Find Similar DNA Sequences

When searching for DNA sequences, imperfect matches containing gaps or mismatched bases can be found, and search performance has been optimized.

Supercoiled DNA Migration

When simulating agarose gels, the migration of uncut circular sequences can be visualized, and supercoiled MW markers can be used.

ssDNA Sequences

A single-stranded DNA (ssDNA) sequence can now be created or imported, with support for feature annotation and sequence manipulations.

Optimized History View

When editing sequences, the history is compressed to allow efficient storage as well as Undo for large sequences.

Additional Protein Feature Types

The set of supported protein feature types has been extended, including support for the misc_feature type.

Sequencher File Import

Sequencher files can now be imported into a SnapGene collection.

SnapGene 5.1

Released 4/2020 | SnapGene 5.1 Detailed Release Notes

SnapGene 5.1 provides enhanced flexibility for displaying and annotating sequences. Highlights include an improved layout for linear maps, an optional split view for sequence windows, more versatile controls for enzyme visibility, and links between related folders in different areas of a SnapGene collection.

Better Linear Maps

Enzyme sites and other annotations in a linear map are now allowed to overlap, thereby reducing map height while preserving legibility.

Optional Split View

A DNA or protein sequence window can be split to show two different views, or two versions of the same view.

Enzyme Visibility Controls

Like features and primers, individual enzymes can now be shown or hidden using check boxes.

Links Between Collection Areas

When a SnapGene collection stores related files in the DNA Files, Protein Files, and Miscellaneous Files areas.

Flexible Choice of Reference Type

When adding references to the Description Panel, a variety of reference types are now available.

Adjustable Threshold for Feature Detection

When importing features from another SnapGene file or detecting common features, the match threshold can be adjusted between 80-100%.

Batch Edits in Collections

A SnapGene collection now supports batch edits of multiple files for flipping sequences, importing features or primers, detecting features or primers, performing BLAST searches, and specifying entries in the Description Panel.

Optional Stripes for “A” Traces

In a sequence trace file, the “A” trace can be displayed with stripes to support researchers with color vision disabilities.

Pre-defined “Type IIS Enzymes” Set

Type IIS enzymes, which are used for Golden Gate assembly, can be displayed using a pre-defined enzyme set.

SnapGene 5.0

Released 9/2019 | SnapGene 5.0 Detailed Release Notes

SnapGene 5.0 adds new capabilities and display options including pairwise alignment, import from the Ensembl database, support for directional TOPO cloning, and improved tools for alignment to a reference DNA sequence.

Pairwise Alignment

Pairs of DNA or protein sequences can be analyzed by local, global, or semi-global alignment.

Import from Ensembl

Gene or transcript data from the Ensembl genome browser can now be imported directly into SnapGene.

Directional TOPO® Cloning

A new interface simulates directional TOPO® cloning into topoisomerase-activated vectors.

Flexible Alignment to a Reference

The interface for aligning to a reference DNA sequence has been enhanced. Controls for various display options are more intuitive, and alignment can be restricted to a designated strand or region of the reference sequence.

Draggable Nonaligned Ends

For a sequence that has been partially aligned to a reference DNA sequence, the nonaligned end portions can now be dragged out and visualized.

Anza™ Enzymes

The Anza™ enzyme system from Thermo Fisher (Invitrogen) has been incorporated into SnapGene’s enzyme database.

Customizable Background Color

The background color for the SnapGene interface can be changed.

Visibility Controls for Feature Types

Features can be shown or hidden based on feature type.

New Options for Amino Acids

Amino acids in a translated feature can be set to lowercase, and a stretch of amino acids can be copied in 3-letter format.

Codon Frequencies Calculator

A codon frequencies table can be generated for one or more translated features.

DNA-to-Protein Alignment Conversion

A selected region of a DNA alignment can be translated to generate the corresponding protein alignment.

Intron Annotation for an Aligned cDNA

When a cDNA is aligned to a reference genomic DNA sequence, the cDNA can be used to create a feature in which gaps are annotated as introns.

Extended Selection Endpoints in Maps

Selections are now marked with extended lines, which clarify the selection endpoints and also enhance visibility for small selections.
