As each reading is entered into a project database it is given a unique number. The first is numbered 1, the second 2 and so on. Their reading names are read from the ID line in the experiment files and copied into the database. As new readings are created and existing ones removed the reading numbers change in an unpredictable fashion. Hence when taking notes on a project always record the reading name instead of the reading number.
Many options ask for a reading or contig identifier.
A contig identifier is simply any reading name or number within that contig. Generally when prompting for a contig or reading name a default is supplied. This is the last name you used, or if you've only just opened the database, the name of the longest contig in the database. This page is maintained by staden-package . Last generated on 20 March 2000.
