    (Requested by Bandar)

Enhancements

  • Reduced the height of linear maps by enabling items to be superimposed without sacrificing legibility.
    (Requested by Vishal Chaudhari)
  • Changed the defaults to show HF® and FastDigest® information in the Restriction Enzymes dialog, while allowing these defaults to be adjusted.
    (Requested by Silvana Jirka)
  • Enhanced the File > Export cascading menu to enable export of multiple files or a list of files from a collection.
    (Requested by Gurumoorthy Krishnamoorthy)
  • Added support for a color attribute when importing features from GFF3 format.
    (Requested by Matthew Kirk)
  • Added support for specifying the line break characters when exporting to text file formats.
    (Requested by Tim Fallon and Tom Chappell)
  • Enabled long map labels to span two lines in circular Map view.
    (Requested by Chun Cao)
  • Configured Sequence view to retain visibility of the scrolled region when toggling horizontal scrolling.
    (Requested by Kengo Adachi)
  • Enhanced the flexibility of code number display in collection lists.
    (Requested by Tim Nierhaus)
  • Added a keyboard shortcut for "Import UniProt Sequences".
    (Requested by James Wright)
  • Enabled colors in multiple sequence alignments to be copied to the clipboard.
    (Requested by Monir Ejemel)
  • Provided the option to differentiate "A" traces using a striped pattern for users with color vision disabilities.
  • Provided an adjustable similarity threshold for detecting common features.
  • Enabled the "Make Protein", "Reverse Translate", and "New File From Selection" commands to save the output files to the same collection.
  • Allowed the genetic code to be specified when converting a selection in a DNA alignment to a protein alignment.
  • Ensured that when sorting by Code Number or Alias in a collection, any files with blank entries are placed at the end of the list.
  • Converted SnapGene to a 64-bit application on Windows, thereby improving performance and stability.
  • Ensured that scrollbars are shown only when necessary in Map, Sequence, and History views.
  • Improved the wording in the Restriction Enzymes dialog to make it clearer when a supplier offers multiple variants of an enzyme.
  • Changed the License Agreement dialog so that it is no longer modal, and added support for printing or saving this document using keyboard shortcuts.
  • Made various textual, color, and icon enhancements.

Fixes

  • Configured the Find control to show bottom strand results when using compact format in Sequence view.
    (Requested by Bandar)
  • Prevented extra line breaks from appearing after export of some qualifier values to GenBank and EMBL formats.
    (Reported by Karen Ross)
  • Ensured that all controls in alignment dialogs can be translated into Japanese or Chinese.
  • Ensured that collection folder names for selected items never appear in List view.
  • Enabled scrolling up using Shift + Spacebar in Sequence view.
  • Fixed paging up and down using Function + Up/Down keys, and scrolling to the start or end of the sequence using Function + Left/Right keys.
  • Ensured that ancestral blunt cutters can be shown in green in History view after import from Vector NTI® or other file formats.
  • Prevented unnecessarily asking to add methylation when specifying "Escherichia coli" as the Source for a Natural DNA sequence.
  • Corrected an error with internal array data when editing trace sequences.
  • Ensured that linearizing or circularizing a DNA sequence populates the Sequence Author field with the default author.
  • Configured Enzymes view to show enzyme sites in red upon mouseover in both the main view and the lower map.
  • Corrected codon frequencies for reverse directional ORFs.
  • Ensured that the Description Panel flows to the bottom of the window when zoom controls are shown.

  • Improved the horizontal placement of names and connecting lines for site features in Sequence view.
  • Fixed an issue in which selections in Features and Primers views sometimes remained blue after focus was transferred to the Description Panel.
  • Disabled controls for setting the DNA color when using either compact Sequence view or Map view with features on the DNA line.
  • Fixed issues with displaying enzymes that make two double-stranded cuts when a site is near the end of a linear sequence.
