A chimeric read is a digital DNA sequence (i.e. a string of letters in a file that can be read as a DNA sequence) that originates from an actual chimera (i.e. a physical DNA sequence in a sample) or produced due to misreading the sample. The latter is known to occur with sequencing of electrophoresis gels.
