Release Notes

Version 4.1   details

Version 4.1 offers enhanced flexibility, with a focus on file history trees and the collection interface.

Limit File History Trees

History trees are one of SnapGene’s most powerful features, but large history trees make sequence files unwieldy and slow the simulations. Now you can automatically limit the size of history trees, or manually trim history trees for individual files or sets of files.

View Folders in a Collection

Files in a collection can now be organized in nested folders. The file hierarchy is visible with an optional folder view.

Define Code Numbers for a Collection

For DNA files in a collection, a versatile interface allows specification of the code number format. Newly added or imported files can automatically receive sequential code numbers.

Create a Working Set for a Collection

Files of interest in a collection can be assigned to a "Working Set". Those files are then easily accessed both in the collection and in cloning windows.

Sort a Collection by "Date Created"

Files in a collection can now be sorted either by “Date Added” or “Date Created”.

Choose Enzymes More Precisely

The Choose Enzymes dialog offers new options for specifying the properties of the recognition sequence.

Other changes improve the responsiveness and stability of the software.

Make and Browse Sequence Collections

Store DNA and protein files in specialized folders that allow the contents to be browsed with a flexible interface. Sort the files by name, code number, or date added. Define a “Main Collection” that can be shared by a group, and create personal collections for individual projects.

Search a Collection

Choose from a wide set of options to find files with specific contents or properties.

Annotate Introns Faster

With a translated feature, convert lowercase regions to introns, or convert existing introns to lowercase.

Do a Batch Replacement

Use a collection to perform batch replacement of a specific DNA or protein sequence, feature name, primer name, or sequence author.

Define a Sequence Alias

Display an alternative name for a plasmid or other sequence.

Import Swiss-Prot Files

Open protein sequence files in Swiss-Prot format directly in SnapGene.
