What is CEL file?

The CEL file has been categorized as Data Files. It was designed by Affymetrix. Additionally, the Data Files category contains 1326 of other files. Affymetrix Probe Results Format is most often found on 3 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Linux, Mac OS, Windows. Alternatively, you can use 4 other programs. The GenStat, RMAExpress programs will also handle the file when the multi-aff-py program does not fulfill its role.

How to open CEL file?

The main problem with Affymetrix Probe Results Format is that the CEL file is incorrectly associated with programs. This is manifested by the fact that CEL files open in unusual applications or do not have an assigned program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the CEL file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install multi-aff-py

An often overlooked issue is to make sure that multi-aff-py is installed on the computer. The easiest method is to use the system search engine by entering the program name multi-aff-py in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support CEL files.

Programs to open CEL file

Remember to download programs supporting CEL files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of multi-aff-py with CEL files

However, it may happen that the application itself does not cause the CEL file to open in the multi-aff-py application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the CEL file with the multi-aff-py application.

Step 3. Update multi-aff-py to the latest version

If, however, after binding multi-aff-py with Affymetrix Probe Results Format there were still problems, you should update the program to the latest version.

Step 4. Check for the following problems with the CEL file

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. This suggests truncating the CEL file contents when downloading or copying. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file CEL or the program directory. However, remember that not every infected CEL file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the CEL files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair CEL file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted CEL files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the CEL file to another location.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. If the error persists after closing other programs, wait for a while. However, some background programs may block the CEL file while scanning. If the problem persists, restart the machine.
