Introduction to SeqLab

SeqLab provides a graphical way to work with the GCG program.

Instead of typing commands with options, you choose programs from menus and choose options by clicking on check boxes.

Results are displayed on screen in a variety of windows - text, graphics, and a multiple sequence editor.

SeqLab is a project-based program.

All of the sequences and the results produced by the operation of GCG programs on those sequences is stored in a project file.

SeqLab has two different user interfaces or modes of operation: Main List mode and Editor mode.

The Main List is a list of sequences, list files and multiple alignments in a project.

The Editor mode is used to view and manipulate sequences.

The Editor displays multiple sequences one per line.

Sequences can be viewed as multicolored text or as graphical representations of features.

Graphics output generated by GCG programs can be viewed directly in separate windows.

Key features of SeqLab:

multiple sequence editor allows direct viewing and editing of alignments generated by PILEUP

greatly simplifies the process of selecting groups of sequences or regions within sequences for GCG operations

direct viewing of graphics output

makes all GCG programs and options available with a mouse click, greatly encourages experimentation with new programs and options

emphasizes multiple alignments and features as the focus of work in GCG
