Classifier Session is the reference to the classifier session on which this VI operates.

Thumbnail Image In is the reference to the image that will store the thumbnail image of the sample specified by Sample Index.

error in (no error) describes the error status before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

	status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
	code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.

Sample Index is the index of a sample in the classifier session. The samples are indexed in the order in which they were added to the session, starting with 0.

Note  Set this parameter to –1 to get only the Number of Samples value.

Feature Vector is the feature vector entered in the IMAQ Add Custom Sample VI.

Note  Note If the session referenced by Classifier Session is not a custom session, Feature Vector is empty.

Classifier Session (dup) is a reference to the session referenced by Classifier Session.

Thumbnail Image Out is the reference to the image that stores the thumbnail image of the sample specified by Sample Index.

Class is the class to which the sample specified by Sample Index belongs.

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.

	status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
	code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.

Number of Samples is the total number of samples in the classifier session.
