How can I copy feature annotations from one file to another?
Open the Destination File
Open the file that will receive the imported features.
In this example, the destination file has no features. If the destination file already has features, SnapGene will not duplicate existing features by default, but will offer the option of importing duplicate features.
Specify the Source File
To specify the source file, click Features → Import Features from... . You can import features from SnapGene, BED, GFF3 or GTF files types.
In the Import Features from... dialog, choose a source file that has the desired feature annotations, then click OK.
View Detected Features and Specify those to Import
A second dialog will list any detected features that can be imported. If desired, click the uncheck the option for "Full Descriptions to make the list more compact.
The Add column indicates which features will be imported. To change the default choices, click the relevant check boxes, then click Add [N] Features.
View the Imported Features
The imported features will be added to the destination file.
Save to keep the newly added features.
