-Signals will be populated by data collected from test plan but can also be populated by data from previous runs. Signals can be easily toggled by clicking on the Calculate modal checkbox associated with it.  Signals can be filtered by DOF and direction.  Selections can be inversed or simultaneously all selected or unselected via the right-lick menu. \\ \\ The Signals can be validated to show which are compatible for simultaneous data processing using the validate button found in the upper right of the Signal Candidates for modal calculation window \\  \\  Any Runs from the current test can be easily loaded into the page by right clicking on the save file under Run folders. \\ {{:modal:modal-analysis:open_to_mds.png?}} \\ \\ Separate data files can also be added once they are loaded under the similarly named tab

-When a signal is left clicked, the FRF collected from the signal will display in the upper right corner of the screen.

 The **Modal Data Selection** tab is the first step of Modal Analysis in EDM. Here you choose which measured signals will be used to calculate the modal parameters, check that each signal has the correct Degree of Freedom (DOF) label, and confirm that all the signals are compatible before you move on to **Band Selection**. The **Modal Data Selection** tab is the first step of Modal Analysis in EDM.
