For many operations it is convenient to be able to process sets of data together - for example to calculate a consensus sequence for a subset of the contigs. To facilitate this Gap4 uses lists.
Most commands dealing with files containing the names of readings or contigs can now deal with either files of filenames or lists. Their primary use is for temporary files that have been produced as the output from one function in order to be used as the input to another. When selecting list names from within dialogues the "browse" button will display a window containing all the currently existing lists. To select a list simply double click on the list name. Alternatively the name may simply be typed in.
The List menu on the main menubar contains commands to Edit, Create, Delete, Copy, Load, and Save lists. Some of these display a list editor. This is simply a scrollable text window supporting the usual editing facilities (see below). The "Clear" button clears the list. The "Ok" button removes the list editor window. It is not necessary to use "Ok" here before supplying the list name for input to another option. For information on the editing commands available see section Text Windows.
