Many people use "chimeric reads" to describe a type of noise that occur during PCR or sequencing where the bases from two different molecules are reported as one read and the alignments of that read become split when it aligns back to the location of the two original molecules.

WebChimeras are sequences formed from two or more biological sequences joined together. Amplicons with chimeric sequences can form during PCR. Chimeras are rare with shotgun sequencing, but are common in amplicon sequencing when closely related sequences are amplified.
