What is an FSTA file

FSTA files mostly belong to Geneious Prime. FSTA files are FASTA formatted DNA sequence data files used in bioinformatics.
This file stores genetic sequences in a plain text format. It typically starts with a header line marked by the '>' symbol followed by lines containing nucleotide information.
These files serve to:
  • Store raw DNA sequence data
  • Provide aligned sequences for analysis
  • Exchange genetic information between research tools
  • Specialized software such as Geneious Prime, DNASTAR Lasergene SeqMan Pro, and tools like SnapGene use and support this format.
    FilExt.com tip: You can open an FSTA file in a dedicated bioinformatics application for detailed sequence analysis, or in a basic text editor for a quick look at the raw data.

    How can I open an FSTA file?

    You need a suitable software like Geneious Prime to open an FSTA 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 FSTA file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a FSTA file directly in the browser:. Just drag the file onto this browser window and drop it.

      See the previous paragraphs to learn more about the main application. FSTA files are often referred to as Geneious Prime data files because this type of file is primarily created or used by this software.
    2. Geneious Prime
      An FSTA file is a plain text file used to store DNA or protein sequences in the FASTA format. The FASTA format, developed by Bill Pearson, begins with a single-line description starting with a greater-than symbol (>) followed by the sequence identifier and optional description. Subsequent lines contain the sequence itself, typically using single-letter codes for nucleotides (A, C, G, T) or amino acids. FSTA files are commonly used for sequence analysis, alignment, and database searching in bioinformatics. This file format is classified as bioinformatics.

    How to solve problems with FSTA files

    • Associate the FSTA 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 FSTA file format. Search, therefore, e.g. on the manufacturer website after an available Geneious Prime update.
    • To make sure that your FSTA file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
