What are the columns in rdanns output?
The output contains one annotation per line; from left to right, each line contains the time of the annotation in hours, minutes, seconds, and milliseconds; the time of the annotation in sample intervals; a mnemonic for the annotation type; the annotation subtyp [sic], chan, and num fields; and the auxiliary information string, if any. The meanings of the annotation type mnemonics and of the other fields are discussed here.
