Importing Data

Whole File menu items.

To import a single data set directly from the MATLAB workspace, there are two variants:

1. To create a data set from input and output signals available in the workspace, select Import... from the Data pop-up menu.
2. If the data set already exists in the workspace in the correct SITB format, then import it directly by pressing the hotkey d when the pointer is in the ident window.

In either case a dialog box opens and asks for relevant information, such as sampling interval and time span. Notes can also be added. This information will follow the data set throughout.

(file idimp.htm) Importing Models Whole File menu items.

Earlier created models in the Toolbox's THETA-format can be imported from the MATLAB workspace using the Models pop-up menu. If the model originally was exported from ident, it will be imported together with an *_info variable that contains relevant information.

The following example illustrates how the *_info variable can be used to maintain essential information, when a model has been modified by MATLAB workspace commands:

Export the model `mymodel` to workspace. The do the following commands:
`mycmodel = thd2thc(mymodel); % Transforming it to cont. time.
mycmodel_info = str2mat(mymodel_info,"mycmodel = thd2thc(mymodel)");
% Updating the info variable
` If you now import back `mycmodel` into ident, it will carry the correct notes and diary.

(file idimp.htm) Ident Sessions A session is the status of all data sets and all models on the Model/data board(s) including their diary and notes. A session can consist of an arbitrary number of extra boards (which can be opened under the Options menu in the main ident window.

Sessions are opened, closed, and saved under the main ident window's File menu.

Only one session can be open at any time. You can however merge another, previous session into the current one, using the File menu.
