What is an FCS file

FCS files mostly belong to Flow Cytometry Standard by International Society for Advancement of Cytometry. FCS stands for Flow Cytometry Standard File. FCS file extension is a standard data file format associated with flow cytometry experiment data. It is one of the many standards developed by the International Society for Advancement of Cytometry (ISAC).

Main Use: Flow cytometry is a method used in the counting, examining and, sorting of microscopic particles suspended in a fluid stream.FCS file format has been accepted as the standard file format for reading and writing the information obtained from flow cytometry experiments. The FCS specification standard was initially developed and subsequently maintained by the International Society for Advancement of Cytometry (ISAC). The FCS file type consists of a combination of textual and binary data. The layout of the file consists of a header segment, text segment, data segment, optional analysis segment, CRC value, and other optional segments. The header segment consists of an ASCII string that contains the FCS standard used in the file.
Other Uses: FCS file extension is also used by Faircom Corporation's c-treeACE application, a database engine used in the development of fast database applications. The FCS file consists of numerous types of information used by the c-tree server application for internal purposes. FCS file type is also used as a spectrum server log file by VisualRadio, global remote control and audio analyzer application used by several armies and police organizations. FCS file extension is also known to be used by the digital photo management application, Canon ZoomBrowser.

How can I open an FCS file?

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

FCS file format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). If the file extension or signature does not match the file format, errors will occur when opening or editing the file. If there are problems opening a file, you must first determine the file format used. Our evaluation of the FCS files is as follows:

The FCS extension is very commonly used. This FCS file itself is among the most popular common file types and mainly uses a defined FCS format. But the following two file formats are common:

95% of all FCS files are associated with Flow Cytometry Standard format. They consist of unreadable binary data. The average file size is 860 KB with most files being between 54 KB and 11 MB in size. It is a modern file type. Certain words are almost always found in the files, such as FCS3. Files like these have the following tags: specimen, sample, control, tube, group, cells, build, stained and data.
1% of all FCS files are using the well-known PDF file format to store the data. PDF is short for Portable Document Format, is a file format to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. The contents of these files cannot be read by a human; only a computer program can interpret the data. The file size is in the range of 790 KB to 1 MB.

All the rest of the FCS files (4%) have different formats. These files are often connected to experiment, controls, compensation, unstained, live, source or fitc. If you want to find out which format your FCS file belongs to, just click on the button "Choose your .fcs file to analyze".
