| this example will time normalize a signal (in this case knee flexion angle) between events (**rhs** to **rhs**) for right knee angles and (**lhs** to **lhs**) for left knee angles, and compute a **global** mean and standard deviation. a meta-command will be used. \\ add the **global_normalized_signal_mean** command to the pipeline. double click on the command to launch the dialog. gnsm1.jpg select the **rknee_angle** signal and the event sequence (e.g **rhs** to **rhs**) and select add a new signal gnsm2.jpg select the **lknee_angle** signal and the event sequence (e.g **lhs** to **lhs**) and select add a new signal gnsm3.jpg enter in the **p2d result signal name** and the select **create standard deviation button** gnsm4.jpg when you select **ok** the text representation of the command should be as follows: <code> global_normalized_signal_mean /signal_types=link_model_based+link_model_based /signal_names=rknee_angle+lknee_angle /signal_folder=original+original /signal_components=x+x /start_label= /end_label= /event_sequence= rhs+rhs++lhs+lhs ! /exclude_events= /result_name=knee_flexion ! /result_folder=original /normalize_points=101 /create_standard_deviation=true ! /calculate_per_file=false ; </code> **note:** if **calculate_per_file=false**. signals from all active files are used to compute the mean **note:** if **calculate_per_file=true**. the mean value is computed for signals from each active files. the global mean value is then the mean value of the mean values. **note:** that the output signal is a p2d signal, which is associated with every file. the resulting signal, therefore, is stored in the **global_workpace** \\ the meta-command **create_global_means_for_left_right** will be used for processing all 3 components of a number of model based signals using one pipeline command. let the original cmo file contain the following signals: rankle_angle rknee_angle rhip_angle lankle_angle lknee_angle lhip_angle let the events for heel strike be labeled **lhs** and **rhs** and that mean signal should be computed from heel strike to heel strike. \\ the pipeline script for the **create_global_means_for_left_right** meta-command is below: <code> create_global_means_for_left_right /type=angle /joints=ankle+knee+hip /start_event=hs /end_event=hs ; </code> the following should be cut and pasted into the **create_global_means_for_left_right.v3m** meta_command folder which should be placed within the plugins folder. <code> ! begin_meta ! meta_cmd_name=create_global_means_for_left_right ! meta_param= type  : string ::yes ! meta_param= joints  : string ::yes ! meta_param= start_event  : string ::yes ! meta_param= end_event  : string ::yes ! end_meta ! create a global_normalized_signal_mean event for left and right ! sides with common labels (e.g. rhs and lhs) for_each /iteration_parameter_name=index1 /items=::joints ; for_each /iteration_parameter_name=index2 /items=x+y+z ; global_normalized_signal_mean /signal_types=link_model_based+link_model_based /signal_names=r&::index1&_&::type+l&::index1&_&::type /signal_folder=original+original /signal_components=::index2+::index2 /start_label=r&::start_event+l&::end_event /end_label=r&::start_event+l&::end_event ! /event_sequence= ! /exclude_events= /result_name=::index1&_&::type&_&::index2 ! /result_folder=original ! /normalize_points=101 ! /create_standard_deviation=false ! /calculate_per_file=false ; end_for_each /iteration_parameter_name=index2 ; end_for_each /iteration_parameter_name=index1 ; </code> }}}}}}
