| | ===Analysis window Status pane=== |
|
| |
|
| ===Analysis window Model Cache pane===
| | The Status pane is both informational and interactive. The appearance of the pane visually indicates the status of the analysis. It has an initial appearance before you load data into the Analysis window, it has a different appearance after you load data into the Analysis window, and it has yet another appearance after you create an item from the loaded data. For example, as shown in the figure below, the X calibration control (the primary location for loading data in an Analysis window) has one appearance before you load calibration data and it has another appearance after you load calibration data. In addition, a "P"� appears after the X control and before the Model control, which you can use to access preprocessing methods for the loaded data. After you create a model based on the loaded data, the Status pane has yet another appearance. |
|
| |
|
| Data that is used to create models and predictions during data analysis as well as all of the models and predictions created from this data is automatically cached. After a model is created, the model and the data used to create it are added to the cache. If new data is loaded and a prediction is made, this new data and the prediction are added to the cache. Every time you edit data and create a new model or prediction from the data, each version of the modified data and the corresponding model or prediction are added to the cache. The Model Cache pane displays this complete history of all your cached items-all of the data that was used to create models and predictions during data analysis as well as all of the models and predictions that were created from this data-in a hierarchical view.

|
| To reload a previously created model:
| |
| # Set the Model Cache view to the mode which best organizes the list to help you find the item desired (see the [[AnalysisWindow_ModelCachepane#Model Cache pane view|Model Cache pane view]] descriptions for suggestions.)
| |
| # Locate the model to load in the list (Note that after other sorting criteria are met, models on a specific branch are sorted by date in all views.)
| |
| # Double-click on the old model to load it into the Analysis window. The calibration data corresponding to the model will also be automatically loaded (if it is available in the cache.) Right-clicking the model will give other options - see [[AnalysisWindow_ModelCachepane#Manipulating cached items|Manipulating cached items]].
| |
| For more usage hints, see the [[AnalysisWindow_ModelCachepane#Model Cache pane view|Model Cache pane view]] descriptions below.
| |
|
| |
|
| '''Note:''' By default, the Model Cache pane is turned on when Solo first opens. You can close the Model Cache pane by clicking the Close ("X") button in the upper right hand corner of the pane. To turn the Model Cache on again, on the Tools menu on the Analysis window, click View Cache, and then select a viewing option. Models and data are cached even if the Model Cache pane is not open.
| | In addition, just as the appearance of the pane varies based on the analysis status, the information that is displayed for a control varies based on the analysis status. For example, before you start an analysis, place your mouse pointer the on the X calibration control to view instructions about working with the control. After you load data, place your mouse pointer on the control again to view not only information about the loaded data, but also, different instructions about working with the control. |
|
| |
|
| Multiple options are available to you for changing the Model Cache view, managing your cache, and manipulating cache items. See:
| | ''Information that is displayed in the Status pane'' |

|
| ===Model Cache pane view===
| | Every control in the Status pane is both left-clickable and right-clickable. What happens after you click on a control depends not only on the control itself (is it an X or Y control or is it a Model or Prediction control), but also, on the type of click (left or right) and the analysis status. For example, if you left click an empty X calibration control, then the Import dialog box opens, and you must select a file to import. If you left click or right click the X calibration control after you have loaded data, then a menu opens with options for manipulating (loading, importing, editing, plotting, and so on) the data. Again, as shown in the figure below, the options that are enabled on the menu depend on the analysis status. |
|
| |
|
| The options to change the Model Cache pane view are found in two locations:
| | ''Status pane context menu'' |
|
| |
|
| * In the Model Cache pane itself under Cache Settings and View
| | [[Image:AnalysisWindow_StatusPane.16.1.3.jpg|426x201px]] |
| * On the Tools menu (the View Cache option) for the Analysis windows
| |
|
| |
|
| :''Options to change the Model Cache pane view'' | | Note: All of the actions that are available in the Status pane are also accessible through the Analysis window menus and toolbar, but it is typically easier to work directly in the Status pane. |
| | |
| ::[[Image:Model_cache_settings_options.png|171x56px]]
| |
| | |
| You can select from three different organizational views:
| |
| | |
| * View Cache by Lineage-In the View Cache by Lineage view, the cache items are sorted by the parent data item. Under the parent data item, the child items (modified data, model, and predictions) are sorted by the timestamps at each modification point.
| |
| : This is a convenient view to use in identifying a set of models which were all created from a specific data set or ''version'' of a data set (such as a specific data set with different sets of included variables and/or samples.)
| |
| | |
| :''View Cache by Lineage view''
| |
| | |
| ::[[Image:Model_cache_view_lineage.png|247x288px]]
| |
| | |
| * View Cache by Date-In the View Cache by Date view, all cached items are simply sorted by creation date in chronological order.
| |
| : This is a convenient view to use when attempting to locate a model or data which was used on a specific date. For example, to reload a model which you knew was built yesterday, switch to the Date view, locate yesterday's date, and expand the tree. All data and models used on that day will be listed. Reload any model by double-clicking it.
| |
| | |
| :''View Cache by Date view''
| |
| | |
| ::[[Image:Model_cache_view_date.png|247x288px]]
| |
| | |
| * View Cache by Type-In the View Cache by Type view, all cached items are simply sorted by object type-data, model, or prediction.
| |
| : This is a convenient view to use when attempting to locate a specific type of model when the data used and model's created date are not known. All data, models, and predictions are listed under their own branch, and then sorted by name (for data), type (for models and predictions), and date. For example, to locate an MCR model you know you created on some previous date, switch to the Type view, expand the Models branch, and locate the MCR models in that branch. You can then reload any model by double-clicking it.

| ===Cache management===
| |
| | |
| Several options are available to you for managing your cache. You can modify all of these options in the Options dialog box.

| ===Moving/Changing a Cache===
| |
| | |
| You can copy and move your Model Cache folder to a new location without any special consideration. When moving to a new computer, copy the cache folder to the new EVRI [[evridir | home folder]] and restart Matlab. Once the folder is in the new location select '''File/Change Cache''' from the Workspace Browser and select the new folder. The cache will refresh automatically.
| |
| | |
| From the Workspace Browser '''File>Change Cache''' menu item. From the Matlab command line the cache folder location can be change with:
| |
| | |
| modelcache('changecachedir','path/to/new/location')
| |
| | |
| If you move your modelcache and experience problems getting the Model Cache to recognize the new location you may need to clear your preferences (matlabprefs.mat) file. Contact helpdesk@eigenvector.com for more details on how to do this.
| |
| | |
| ===Exporting and Importing Models===
| |
| | |
| Models can be exported from the cache via the right-click menu '''Export For Cache''' item. This will export the model and the data used to create it (if available) to a MAT file. The file can then be Imported into a different cache. To import a cache model, expand the Cache Settings and View leaf and click the '''Import Model' leaf.

Analysis window Status pane
The Status pane is both informational and interactive. The appearance of the pane visually indicates the status of the analysis. It has an initial appearance before you load data into the Analysis window, it has a different appearance after you load data into the Analysis window, and it has yet another appearance after you create an item from the loaded data. For example, as shown in the figure below, the X calibration control (the primary location for loading data in an Analysis window) has one appearance before you load calibration data and it has another appearance after you load calibration data. In addition, a "P"� appears after the X control and before the Model control, which you can use to access preprocessing methods for the loaded data. After you create a model based on the loaded data, the Status pane has yet another appearance.
Different appearances of the Status pane
In addition, just as the appearance of the pane varies based on the analysis status, the information that is displayed for a control varies based on the analysis status. For example, before you start an analysis, place your mouse pointer the on the X calibration control to view instructions about working with the control. After you load data, place your mouse pointer on the control again to view not only information about the loaded data, but also, different instructions about working with the control.
Information that is displayed in the Status pane
Every control in the Status pane is both left-clickable and right-clickable. What happens after you click on a control depends not only on the control itself (is it an X or Y control or is it a Model or Prediction control), but also, on the type of click (left or right) and the analysis status. For example, if you left click an empty X calibration control, then the Import dialog box opens, and you must select a file to import. If you left click or right click the X calibration control after you have loaded data, then a menu opens with options for manipulating (loading, importing, editing, plotting, and so on) the data. Again, as shown in the figure below, the options that are enabled on the menu depend on the analysis status.
Status pane context menu
Note: All of the actions that are available in the Status pane are also accessible through the Analysis window menus and toolbar, but it is typically easier to work directly in the Status pane.
