.CEL filtypenavn

En CEL-fil er en datafil oprettet af Affymetrix DNA microarray billedanalysesoftware. Den indeholder data udtrukket fra "prober" på en Affymetrix GeneChip og kan gemme tusindvis af datapunkter, hvilket kan gøre den stor i filstørrelse. CEL-filer kan behandles af softwarealgoritmer og visualiseres på et 2D-gitter som en del af et samlet genomeksperiment.

En Affymetrix GeneChip er en biologisk chip, der indeholder et mikroarray, der er gyldigt til ét eksperiment. For at skabe disse chips er et glas- eller siliciumglas arrayet med prober, som rapporterer ekspressionsniveauer (intensiteter) som perfekt match (PM) og mismatch (MM) værdier, baseret på om de er komplementære til den originale DNA-prøve. Disse værdier kan bruges til at studere DNA-ændringer, kaldet single-nucleotid polymorphisms (SNP'er), som bruges i menneske- og dyresygdomsforskning.

CEL-filformatet har flere versioner, som bruger forskellig formatering. For eksempel bruger version 3 ASCII-tekstformatering, mens version 4 bruger et binært format.

NOTE: CEL files require a corresponding .CDF file, which is the dictionary for the raw probe-level data stored in the CEL file. MATLAB has a built-in function called affyread that can be used to read CEL files in the Windows version of the software.

Script used by Celestia, a free space browsing application; written using a specific Celestia syntax and includes commands for moving the viewing perspective throughout the universe; used for creating 3D universe tours.

CEL files may also include more advanced features, such as instructions to load custom 3D models into the space tour. They can also include captions to provide interesting facts to the observer.

If you download or receive a CEL file, you can open it by double-clicking the file, or by selecting File → Run Script... from the application menu and then choosing the CEL file.

The CEL format has been replaced by the .CELX format in recent versions of Celestia. However, Celestia still supports CEL files. The newer CELX format uses the Lua scripting language, which is more expressive and powerful than the CEL language.

NOTE: CEL files are saved as plain text files and are edited using a text editor.

Audio file used by Adobe Audition, an audio production application; saves an audio loop that was originally in the .MP3 format but was modified by the software so is it suitable for looping.

Adobe Audition includes several royalty free loops with the software installation.

File used by Battery 3, a program that creates drum rhythms and sounds; contains sound properties for a particular drum sound within a Battery 3 drum sound cell; used to modify drum samples with additional effects, such as reverb, tone, or compression.

Cellebibliotek skabt af MicroStation, et CAD-program, der bruges til at skabe 2D- og 3D-designudkast; gemmer geometri, symboler og andre udkastoplysninger for et objekt; bruges til at gemme byggeklodserne til at generere design af højere orden.

CEL-filer kan eksporteres til .DWG- og .DXF-formater ved hjælp af MicroStation.

Animation oprettet i FLIC-formatet; gemmer en række rammer, men gemmer ikke dele af tidligere rammer, der ikke er ændret; bruger mere almindeligt .FLC- eller .FLI-udvidelserne.
