#!N  #!Rcatstr Structuring #!N #!EC #!N #!N These tools manipulate Data 
Explorer data structures. Their functions include the creation of hierarchies, selection 
of elements in a hierarchy, allowing operations on components other than 
"data," manipulation of Field or Group components, and determining which branches 
of a visual program are to be executed. #!N #!I0 #!N

 #!Lcollect,dxall788 h Collect  #!EL  #!EF #!I50 #!N Collects Objects into a Group. For example, 
you can use Collect to collect a streamline, an isosurface, and 
a light. You can then pass the collection to the Image 
tool. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lmultigr,dxall789 h CollectMultiGrid  #!EL  #!EF #!I50 #!N Collects Objects 
into a Multigrid (a Group that will be treated as a 
single data Object). #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lcollecn,dxall790 h CollectNamed  #!EL  #!EF #!I50 #!N 
Collects Objects into a Group (like Collect) but allows each Object 
in the Group to be given a name. #!N #!I0 #!N 
 #!F-adobe-times-bold-r-normal--18*    #!Lcollecs,dxall791 h CollectSeries  #!EL  #!EF #!I50 #!N Collects Objects into a Series. You 
give each element of the series a series position (e.g., a 
time tag). #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lcopycon,dxall800 h CopyContainer  #!EL  #!EF #!I50 #!N Copies 
the top container Object. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lextract,dxall845 h Extract  #!EL  #!EF #!I50 
#!N Extracts a component from a Field (e.g., the "colors" component). 
#!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Linquire,dxall877 h Inquire  #!EL  #!EF #!I50 #!N Returns information about 
the input Object (e.g., data type, number of elements, etc.). #!N 
#!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Llist,dxall885 h List  #!EL  #!EF #!I50 #!N Concatenates several items into 
a single list. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lmark,dxall893 h Mark  #!EL  #!EF #!I50 #!N 
Marks a specified component in a Field as the data component. 
Many modules operate only on the "data" component. Thus the Mark 
module allows modules to operate on components other than data (e.g., 
"positions" or "colors"). If a "data" component already exists, it is 
preserved in a "saved data" component. You can restore it by 
using the Unmark module. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Loptions,dxall898 h Options  #!EL  #!EF #!I50 
#!N Associates attributes with an Object. For example, plotting options such 
as marker type can be specified by adding attributes to the 
line. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lremove,dxall921 h Remove  #!EL  #!EF #!I50 #!N Removes a 
specified component from a Field. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lrename,dxall922 h Rename  #!EL  #!EF 
#!I50 #!N Renames a component in a Field. For example, you 
could rename the "colors" component to "front colors" to get only 
front-facing colors. You should be aware that component names have special 
meanings to modules using them. See  #!Ldatmod,dxall197 h Understanding the Data Model  #!EL  in IBM Visualization Data 
Explorer User's Guide. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lreplace,dxall925 h Replace  #!EL  #!EF #!I50 #!N 
Replaces a component in one Field with a component from another, 
or with an input Array. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lselect,dxall936 h Select  #!EL  #!EF 
#!I50 #!N Selects members out of a Group or elements from 
a list. two isosurfaces, a streamline, and a mapped plane. You 
could then use the  #!F-adobe-times-bold-r-normal--18*   selector #!EF input to the module 
to choose which of these is the output of the module. 
#!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!Lunmark,dxall972 h Unmark  #!EL  #!EF #!I50 #!N Undoes the action 
of the Mark module. It moves the "data" component back to 
the component you specify, and the "saved data" component is restored 
to the "data" component. #!I0 #!N #!N #!N #!N #!N  #!F-adobe-times-medium-i-normal--18*
