.fasta File Extension

Developer: N/A
File type: FASTA Sequence File
You're here because you have a file that has a file extension ending in .fasta. Files with the file extension .fasta can only be launched by certain applications. It's possible that .fasta files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .fasta file?

The .fasta file extension is used for files related to biology. The .fasta file extension is used to describe files that has something to do with nucleic acid, DNA and protein sequences. Aside from this basic information saved in the .fasta format, it also contains headers containing other information such as comments. The .fasta format is usually written in single line that contains the sequence, symbols and names. This file extension is mostly used by files and biological information created using the FASTA program, an application used by biologists and biochemists in terms of recording electronic data about DNA and other information. This software is also used for speedy comparison about nucleotides and other biological data, and this can only be possible if the files are in the .fasta format. These .fasta files usually need software, such as FinchTV, in order to be opened. Other DNA sequencing software like CubicDesign DNA Baser also uses the .fasta file extension.

how to open a .fasta file?

Launch a .fasta file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .fasta file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .fasta files aren't yet associated with it. In this case, when you try to open a .fasta file, you can tell Windows which application is the correct one for that file. From then on, opening a  .fasta file will open the correct application.

4Peaks

4Peaks

4Peaks is a DNA managing software enabling molecular biologists to view, edit and manipulate DNA sequence files. This program is only applicable to Mac computers, particularly OS X10.3 operating systems and higher versions. Plus, this software does not require conversion of file formats as it supports most of the standard DNA sequence files. With the integrated features, DNA sequence analyzing is a lot easier and effortless to conduct using 4Peaks. These include sharper traces, display of high quality DNA sequence data or crop low quality data in a single click, and editing tool for the reduction of missed or erroneous entry by simply double clicking the area. This program also translates sequences automatically with immediate checkup of the consequences of a single mutation, reads standard file formats of DNA sequences, and supports writing and reading of sequence files in various common formats. There are thousands of motifs to select from to create sequence, which make analyzing easier as you can use through color coding and built in plugins.
GeoSpiza FinchTV

GeoSpiza FinchTV

FinchTV is a DNA sequence trace viewer that runs on Windows, Mac, Solaris and Linux. It began as the only chromatogram viewer that can view an entire sequence in a scalable, multi-window view. It provides BLAST searching, views of raw data and the ability to reverse traces and complement sequences. The latest version is version 1.4. Among its added features is the printing option for custom scale settings. It also introduces an optional integration with Geospiza’s GeneSifter Lab Editon. You can keep track of adjustments at your base while working on your data sequencing, edit your trace files and save your data back to a supported relational database with complete history of revisions, share-ability and accessibility though the Web. Geospiza develops software to facilitate and improve genetic research. In data analysis, you will be able to visualize and dig into volumes of data through [NGS] Next Generation Sequencing technology. You save time and costs for data management and complex laboratory workflows. You accomplish your research from samples to results in 4 to 6 weeks. Data analysis, data storage and DNA sequencing are incorporated into a single complete unit.
CubicDesign DNA Baser

CubicDesign DNA Baser

CubicDesign DNA Baser is an application that deals specifically in the field of molecular biology. DNA sequence assembly, automatic sample processing, analysis of DNA sequence, mutation detection, format conversion and sample processing simulations are the CubicDesign DNA Baser’s capability. The user may customize the background, nucleotides and chromatograms. The software may suggest and correction in case of a vague base. And those unclear bases will be highlighted for proper notification. Assembly engine may also be personalized. DNA samples may be assembled and aligned to a referred sequence, import from ABI, SCF, SEQ, TXT, FASTA, GBK formats. Traces may be also viewed and edited, convert the output to Multi- FASTA and other mentioned formats. The metadata in the user's contigs may be integrated automatically, detect or remove the vectors. CubicDesign DNA Baser run in Windows and Mac specifically on this following hardware: 333MHz for the processor, 64 MB of RAM, 1024 x 768 screen resolution, 2 MB Hard Drive space.

a word of warning

Be careful not to rename the extension on .fasta files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .fasta. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
