Viewing DNA sequence files in SnapGene viewer
From RSpace 1.68 we are pleased to be able to offer a new service to view DNA sequence files in collaboration with SnapGene. Currently supported file formats include:
- Genbank (.gb, .gbk)
- Fasta (.fa, .fasta)
- Native SnapGene files (.dna)
- Embl (.embl)
- Lasergene (.seq)
- SeqBuilder (.sbd)
- View images of the files annotated with ORFs and restriction sites
- View ORFs in a table
- View restriction enzyme sites in a table
- View and copy plain-text of the sequence for pasting into another application
You can access this functionality in edit mode, view mode or in the Gallery.
Accessing SnapGene Viewer in a Document
Let's start with a document in View mode into which we've uploaded a DNA file (through drag-and-drop, for example):
Supported DNA files will show with a DNA icon. Click on 'View' to open the Viewer. This will give a visual preview of the sequence. You can pan and zoom by dragging and clicking within the image.
The right-hand panel is for configuring the existing view; the left-hand panel is for changing the view.
You can change the view to see tabular listings of:
- Restriction sites, configurable by type
- Open Reading Frames, configurable by forward/reverse
- Plain text view, for easy copy/paste
Accessing SnapGene viewer in the Gallery
DNA sequence files will appear in the 'Miscellaneous' section of the Gallery. Clicking on the DNA icon will open the viewer.
- At this stage the full functionality of SnapGene is not available - protein sequence files and alignment files are no supported yet. We hope to work with SnapGene to continue this work.
- There is a limit of 20Mb for an individual sequence file; this feature is designed for plasmids / coding sequences rather than large genomic sequences.
