Vector NTI® File Import
SnapGene directly opens multiple types of Vector NTI® files, including:
.gb and .gp | DNA and protein sequences |
.ma4 and .pa4 | DNA and protein archives |
.cep | Contig Express assemblies |
.apr and .aprx | AlignX multiple alignments |
The imported files preserve not only sequence data, but also annotations.
Oligo archives (.oar files) can be used for importing primers into SnapGene .dna files, or can be opened in SnapGene and converted to text files.

Vector NTI® Database Conversion
SnapGene (version 5.1.4 and later) supports wholesale conversion of a Vector NTI® Advance or Vector NTI® Express database to a SnapGene collection. Choose “File > Import > Vector NTI® Database…” .
The folder structure of your Vector NTI® database is transferred to the SnapGene collection.
The parent-descendant relationships in your Vector NTI® database are preserved in the history records of the converted SnapGene files.

Scientists everywhere love SnapGene!

“At Novozymes, we upgraded to SnapGene in 2016 when Vector NTI development and support was discontinued. Molecular biologists are excited about SnapGene due to the user friendliness – they can easily make cloning and primer design in silico, keep track of the history of a plasmid as well verify the nucleotide sequence by sequence alignment. Furthermore, we enjoy the interaction and responsiveness to our wishes for improvements from the SnapGene team.”
