-remove the prefix from marker names.
+===== Remove Prefix From Point Labels =====
-===== command =====
+This pipeline command allows you to remove the specified prefix(es) from [[visual3d:documentation:c3d_signal_types:target_data_type|TARGET]] (marker) names within the active files.
-**remove_prefix_from_point_labels**
+==== Command ====
-! /prefix=
-! /include_cal_file=true
-! /overwrite_c3d_file=false
-**;**
-some motion capture manufacturer's software provides an option to add a prefix to all of the marker labels. this causes visual3d a big problem because visual3d assumes that markers are named consistently between files, especially between the standing trial and the movement trials.
-this command can be used to remove marker prefix from targets.

-===== /prefix parameter =====
+Some motion capture manufacturers' software provides an option to add a prefix to all of the marker labels. This has the potential to cause a big problem when reading these files in Visual3D, since an assumption is made that markers are named consistently between files, especially between the standing trial and the movement trials.
-if the prefix parameter is specified, only this prefix will be removed from the signal names.
+This command can be used to remove the marker prefix from [[visual3d:documentation:c3d_signal_types:target_data_type|TARGET]]s.
-if the prefix parameter is left blank, visual3d looks for the c3d parameter group called "subjects" and the parameter "label_prefixes". this could contain several entries, and visual3d searches the targets for signals containing these names and the prefix is removed from the name.
+=== /Prefix Parameter ===
-we have seen instances where the manufacturer stores these values incorrectly.
+If the PREFIX parameter is specified, only this prefix will be removed from the signal names.
-in this case, the user should manually specify the prefix and the c3d parameters are ignored.
+If the PREFIX parameter is left blank, Visual3D looks for the [[visual3d:documentation:c3d_signal_types:c3d_format#c3d_parameter_format|C3D Parameter Group]] called "SUBJECTS" and the parameter "LABEL_PREFIXES". This could contain several entries, and Visual3D searches the [[visual3d:documentation:c3d_signal_types:target_data_type|TARGET]]s for signals containing these names and the prefix is removed from the name.
-===== /include_cal_file =====
+We have seen instances where the manufacturer stores these values incorrectly. In this case, the user should manually specify the prefix and the C3D Parameters are ignored.
-if true, the model files will be modified as well.
+=== /Include_Cal_File ===
-===== /overwrite_c3d_file =====
+If TRUE, the model files will be modified as well.
-if true, the modified c3d file will be exported.
+=== /Overwrite_C3D_File ===
-use this parameter with caution. it is recommended that the parameter be set to false in most cases so that the new names can be verified. the files can then be exported in an independent command.
+If TRUE, the modified c3d file will be exported.
