About FNA files

FNA files, commonly associated with the FASTA format, are used for storing nucleotide sequences. These files are prevalent in bioinformatics for presenting DNA and RNA sequences. However, using FNA files can be cumbersome due to their plain text format and lack of metadata, which complicates data analysis and sharing.

There are several software solutions for converting FNA files. A popular method within local systems is utilizing FASTA2FA from the NCBI toolkit, which can convert FNA files into other bioinformatics formats like FASTQ, GenBank (.gb), or EMBL. Additionally, Biostrings in R provides a comprehensive set of tools for sequence conversion and manipulation. For Python users, the Biopython library offers versatile functions to convert FNA files into various formats, including CSV and TSV for easier data handling.

Converting FNA files can be challenging due to potential data loss or misinterpretation of sequences, especially when converting to formats like FASTQ that include quality scores not present in FNA files. Additionally, the lack of standardization across tools can lead to compatibility issues.

Despite these challenges, converting FNA files is necessary for effective data analysis and interoperability. This is where Convert.Guru shines, providing a user-friendly platform to drag and drop FNA files for conversion into multiple formats, such as CSV, TSV, and even proprietary formats like Excel (.xlsx). By using Convert.Guru, users can avoid the complexities of standalone software and ensure accurate conversions.

The FNA Converter Story

The history of Convert.Guru began more than 25 years ago in California, when Tom Simondi published the most comprehensive database of file formats on his website. Before that, Tom had worked on Space Shuttle development at the Air Force Systems Command’s Space Division in Los Angeles. He is known as one of the top programmers of the late 1980s.

When Microsoft integrated Tom’s Filext database into Windows XP, it became the leading platform for analyzing and processing file types and formats.

Today, we use the latest technologies to analyze, process, and convert one of the world's largest collections of file formats. We are committed to developing the best FNA converter by continuously improving quality, usability, and reliability.
