As discussed in sections 4.1 and 5.4, data can be loaded with the graphical interface by selecting LOAD Data File under the file menu. The default data directory is initially glmlab/data. This can, however, be easily changed. In the glmlab/data directory, there is a file named dummydta.m which contains basically nothing; the sole purpose of the file is to define the default data directory. To have a different default directory, simply move this file into the appropriate directory. Next time the graphical load data window appears, the default directory will be the directory where this file is located.
