The "Datasets Table" provides a convenient way to manage, reference and select for display all your opened datasets. Use the "Datasets Table" command from the "Datasets" menu on the NMRView control panel to display this table. By default the table will display basic information about the dataset as shown in the following figure. This includes the dataset name, the number of dimensions, the number of "real" dimensions (which refers to the number of frequency domain dimensions, as opposed to dimensions that might be incremented for things like relaxation times), the solvent, a displayable title, and the path to the actual file.

At the top of the window are a row of buttons for interacting with datasets. Their functions are as follows:
- Close
Close the Dataset Table Window
- Mode
Choose one of the display modes (Basic, Structure, Appearance, Properties and Referencing) from this combobox.
- Draw
Select one or more dataset rows in the table (in any mode) and click this button to create spectrum windows with these datasets. When you click the button you'll get the normal "Add Window" dialog prelaoded with a name for the window based on the datasets that are selected. If you have selected more than one dataset the "Rows" and "Columns" settings in the dialog will be preselected to give you a grid of containing enought spectral windows to show all the datasets. If instead you want the datasets superimposed, just change the "Rows" and "Columns" settings both to "1".
- Pick
Select one or more dataset rows in the table (in any mode) and click this button to pick peaks in these datasets. This is only really useful if you have saved reasonable a reasonable default contour level in the datasets as this will be used as the threshold for peak picking, and if there are no regions of the datasets that need to be especially excluded (for example an area around water) from the peak picking. Each dataset will be picked and the peaks placed in a peak list with the "root" name of the dataset (e.g. hsqc for a dataset named hsqc.nv).
- ReadPar
Select one or more dataset rows in the table (in any mode) and click this button to load reference parameters from the ".par" file for each dataset.
- WritePar
Select one or more dataset rows in the table (in any mode) and click this button to save reference parameters to a ".par" file for each dataset.
- Remove
Select one or more dataset rows in the table (in any mode) and click this button to remove the dataset from NMRViewJ.
In Appearance Mode, default parameters that are used whenever a dataset is first assigned to a spectral window are displayed. These include a scale parameter (by which the lvl parameter is multiplied to get actual contour levels and peak intensities), the default contour level, whether positive contours should be displayed and in what color they should be drawn, and whether negative peaks should be displayed and in what color they should be drawn. You can enter new values into the table and then select the row and click "WritePar" to save these new values to a parameter file.

In Reference Mode, various parameters that determine how the spectra is referenced are displayed. As with the Appearance parameters you can change these and then save the values to a parameter file.
