A data file is the collection of data and classification columns that are analysed in GenEx. A data file can only be edited and changed in the Data editor. To change a data file that has already been loaded into the Control panel, you must open it in the Data editor, edit it, save the changes and load it into your project once more. Though, you can make reversible "changes" by altering the settings of your data set in the Data manager. These changes include scaling, grouping, coloring, and inactivation of rows and columns. Any changes made in the Data Manager or through transposition are stored in a data set.
To open a file for editing in the Data editor, choose Edit file in the File menu or press the Edit file button, both found in the main window. Once the data is edited, you can load it into the Control Panel in the following ways. Either press the Load button in the Data Editor to create a new project with one data set containing the file you are currently editing, or choose Load file in the File menu in the main window to create a new project with one data set containing the file(s) you select.
The Control panel handles projects, data sets, data files, as well as the analyses. Several projects may be available in the Control panel simultaneously, each project can contain several data sets, which may contain multiple data files. Pressing Data files in the left part of the Control panel shows the available data files in the active data set of the active project. If you already have an active project in the Control Panel, you can press the Plus button under Data files in the Control panel to add additional data files to the active data set. The Cross button is used to remove a file from the data set.
Data files within one data set are allowed to have different dimensions, but most analyses that handle multiple data files require that they have the same dimensions. Also, managing files in the data set will be inactivated if the data files have different dimensions. If GenEx has disabled the data managing due to different dimensions of the data files in a data set, make sure that the present files in the data set was not transposed when the new file was added. You can see whether a data set is transposed or not in the status bar in the main window. If they where transposed, remove the new file, transpose the older files back to their original form by pressing the Transpose button once more, and add the new file to the data set again. You can easily switch between data files in the active data set in the drop-down list at the top of the main window or under Data files in the Control panel.
Viewing a data file in the Data editor shows the original data, while the View data button in the main window displays the managed data with the active data set's settings. Any reversible transposing or scaling, inactivation of rows or columns made in the Data manger will be shown when you View data. This is the data that is used in the plotting and statistical analyses.
If you want to make changes in a data file to see how it affects your analysis, you can edit the file in the Data editor, save it as a separate file, and then add it to the same data set as the original data file.
