Opening FSA_NT Files

The FSA_NT file type is primarily associated with NCBI BLAST.

FSA_NT	File extension: FSA_NT
	File type:	DNA sequence data file

What is an FSA_NT file?

FSA_NT files mostly belong to NCBI BLAST. FSA_NT files store DNA sequences using the FASTA format.
In these files, a header line that begins with a '>' is followed by one or more lines of nucleotide data (A, T, G, C).
They are used with bioinformatics tools, including NCBI BLAST, to compare and align genetic sequences.
Usage Details:

Contain sequence identifiers and annotations in the header

Hold one or more nucleotide sequences

Are plain text and can be opened with standard text editors

Support sequence analysis and alignment tasks

How can I open an FSA_NT file?

You need a suitable software like NCBI BLAST to open an FSA_NT file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your FSA_NT file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a FSA_NT file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert FSA_NT files:

NCBI BLAST
See the previous paragraphs to learn more about the main application. FSA_NT files are often referred to as NCBI BLAST data files because this type of file is primarily created or used by this software.
NCBI BLAST
The *.FSA_NT file extension represents a text-based format primarily used for storing DNA sequences. It is often employed within bioinformatics tools and databases, notably by NCBI BLAST. Characterized by its FASTA format, an *.FSA_NT file starts with a single-line description header, indicated by a greater-than symbol (>), followed by the nucleotide sequence data. While not a formally defined standard, the .FSA_NT extension serves as a common convention to denote files containing nucleotide sequences in FASTA format, thus distinguishing them from other FASTA files, such as those storing protein sequences. The nucleotide data within these files adheres to the IUPAC nucleic acid codes. The FASTA format's simplicity and readability contribute to its widespread use in sequence analysis and alignment. This file format is classified as Bioinformatics.

How to solve problems with FSA_NT files

Associate the FSA_NT file extension with the correct application.
Update your software that should actually open dna sequence data files. Because only the current version supports the latest FSA_NT file format. Search, therefore, e.g. on the manufacturer website after an available NCBI BLAST update.
To make sure that your FSA_NT file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
