Save Design Matrix
When you are in to Design Matrix window, you can save the current design matrix to a dBase (DBF) file. A Save File dialog asks you for the name of the file to save the matrix in. This option is useful for saving the current design matrix, editing it in a spreadsheet, copying the contents of the spreadsheet into the clipboard, and then pasting the clipboard back into the design matrix.
The Save option is available under the File menu choice of the Design Matrix Window.
