A .CEL file can mean different things depending on context, though in genomics it most commonly refers to an Affymetrix/Thermo Fisher microarray output capturing raw probe intensities, where a chip packed with countless probes is scanned after hybridization and each probe’s brightness is saved into the CEL file—typically mapped by grid coordinates or probe indices—along with metadata, producing raw measurements that must be processed with background correction, normalization, and probe summarization through Bioconductor tools like oligo and supported by files such as .CDF and .CHP.
In animation and graphics, "cel" comes from
classic celluloid sheets, and a CEL file typically represents a single raster frame or layer—often transparent—stacked over backgrounds or other layers, usually appearing in sequences like `walk_001.cel` along with palette files or related images, though because different tools used different CEL variants, some open in standard editors while others require the original software or palette; meanwhile, certain games and niche apps also use `.

CEL` as a custom sprite/texture container, so the extension alone can’t identify it, and the fastest way to figure out which type you have is by checking its origin, nearby files, naming patterns, size, and a quick look in a text/hex viewer to see whether it resembles microarray metadata or a binary art/game asset.
In 2D animation, a "cel" comes from the traditional cel-sheet method where each sheet carried a single layer of art photographed over a background, and digital animation mirrors this by layering characters, shadows, and effects; here, a CEL file is a raster image holding one layer or frame—such as a character pose or lip-sync mouth shape—using transparency so it can be cleanly composited over other layers.
Because ".CEL" exists across several unrelated formats, an animation CEL might be indexed-color, stored in a program-specific structure, or linked to a separate palette file; you’ll usually find them grouped in asset folders (`anim`, `sprites`, `frames`) and numbered sequences, and depending on the variant, they may open directly or require the original software, since each CEL is only a single raster layer used in building the complete animated scene.
To classify a .CEL file quickly, the most reliable move is to examine where it came from, since genomic sources typically point to microarray CELs, whereas art/game pipelines suggest animation layers or asset formats; look at nearby files for confirmation—microarray sets include .CDF or .CHP, while animation/game folders contain many numbered CELs and palette files—and then compare file size, count, and a small header peek in a text/hex viewer to spot either readable array metadata or primarily binary graphics/asset data.
".CEL isn’t a single universal standard" reflects that multiple industries repurposed the extension, leading to cases where Affymetrix CELs record raw intensity data, animation CELs hold raster cels or palette images, and game CELs pack proprietary resources, all under the same extension; because of that, identifying the correct flavor requires either context about its source or a look at file headers and related files.
