Extract a sequence from the read and place it in the read name’s comment section, so a (space separated) ‘key=value’ pair is added to the read name.

Supports multiple region-extraction.

See the tag section for more tag generation options.

(there used to be an ExtractToName step before we introduced tag based analysis)
