I would like to understand better the difference from a chimeric alignment and a multiple-mapping alignment. From the information in the SAM specifications, it seems to me that a chimeric alignment takes place when the part of the query read can map to different places in the reference sequence, whereas a multiple-mapping alignment takes place when the whole query read can map to different places in the reference sequence.

Thus, a read can be chimeric if parts of the reads map to the same chromosome but in different places?

Thanks in advance.
