Batch rename is located under the Edit menu and can be used to edit any ﬁeld in multiple documents at once. It can also be used to batch edit any property of sequences within an alignment or sequence list.
Existing ﬁelds can be replaced with a combination of values from other ﬁelds (e.g. Name replaced with Organism and/or Accession), and ﬁxed text can be added to the beginning or end of existing ﬁelds.
The advanced options (under the More Options button) enables the use of regular expressions to replace a speciﬁc part of one ﬁeld with another property or text string. Click the Help button in this section for more information on formatting expressions.
