MIA Toolbox PCA Quick Start
This example uses the smbread dataset. Load smbread by clicking on Load Demo Data in the tree, then Swedish Knackerbrod. This will load the data into Image Manager. Click on the item in the Loaded Images section to view it and make it the current selected image. Next, click on the export to Analysis button. This will open the Analysis GUI and load smbread.

Once data has been loaded into the workspace, there are several ways to begin building a model. For analysis tools like PCA where only an X block is required, you can right-click on the data icon in the Browser to reveal a list of analysis options. You can also drag the given data to an analysis method shortcut, such as the Decompose PCA shortcut. |
The Analysis GUI will then appear with the given data already loaded. (The large X (block) button in the Analysis GUI will appear depressed indicating the data is loaded - passing the cursor over the button will provide a summary of the X block data.) |
While each analysis type has its own nuances, in general the steps to build a model are:
There is more than one way to accomplish each of the above steps. For example, preprocessing can be set for the X block by
(Hint: Once selected, use the Preprocess/X-block and Preprocess/Y-block menus to save the current preprocessing as the default.) You can quickly view your data by right-clicking on the appropriate button (X or Y) and then select "Plot Data" |
Perhaps the quickest way for new users to complete the remaining steps to build the model is to use the flowchart. |
