Frequently asked questions

How long will my order take?

Please discuss your timeline of order processing with the Lab Coordinator for the most accurate estimated completion date.

When am I billed for services?

The DNA Sequencing Facility sends invoices once a month for the previous month’s sequencing. If your institution requires a purchase order number (or some other identifying number on the invoice), please be sure to include that on your completed order form.

How can I view my processed sequences?

Sequences are delivered as industry-standard text files and data files. There are several software packages available for viewing sequences; here are just a few:


Shows razor-sharp traces, auto-translates sequences, reads the most common sequence file formats, and displays sequence quality data. (Mac)


Biological sequence alignment editor (Windows)


View ABI-formatted automated sequencing files (Windows)

Finch TV

Geospiza’s FinchTV is a popular way to view DNA sequence traces (Linux, Mac OSX, Windows, and Solaris)

What resources are available for searching sequence?

There are a wide variety of sequencing databases available and many ways to search within and across sequencing databases. Here are a few resources we find useful:


The NIH genetic sequence database.


An integrated search and retrieval system that takes information from all of the databases at NCBI.


A set of similarity search programs designed to explore all of the available sequence databases regardless of whether the query is protein or DNA.
