The public version of the NSG voucher specimen database is unfortunately not available anymore due to incompatibilities with new versions of PHP.
The old VoSeq was written mainly in PHP. It used MySQL as back-end and it was designed to run on a local server (for example by installing Apache on your computer) or to run on any commercial server service.
The new VoSeq is written in Python. It uses PostgreSQL as a database back-end and it is designed to run either locally in your own computer or on a remote (commercial) server service.
VoSeq is a database to store voucher and DNA sequence data for phylogenetic analysis. It's a unique database that enables to digitize biological data of museum specimens and molecular data such as DNA sequences, primers and genes.
VoSeq has tools that facilitate the batch upload of lots of voucher data and DNA sequences with a few clicks. It also has BLAST capabilities, meaning that you can find out whether one particular DNA sequence is most similar to other sequence NCBI GenBank. You can also BLAST your sequence against all others in your VoSeq database (see the Documentation for more details).
