Each program uses its own Data File so that the pattern selected in one application does not apply when you work with another program. Much of the work you perform may involve single sequences, that you wish to analyse. Whenever you upload a sequence file onto the GCG server or whenever you edit a sequence file using a non -GCG program make sure that the file has this format. Each line should not be longer than 125 characters. You can use list files with any program that accepts multiple sequences as input.
Some programs produce output files that are list files.
They may include additional information, such as Multiple Sequence Files . However, this extra information will not affect the list file's performance. All programs that work with Data Files have a default Data File, so you don't have to worry about it. The new Data File will be stored in your Working Directory. If you keep the name of the default Data File and run a program, it automatically finds your personal Data File and uses it for the analysis.
