This example illustrates how a 7-step time series of a single 
scalar field might be imported. The field is on a regular 
5 * 5 grid, the data are connections dependent, and the 
style is record. #!CForestGreen #!N #!N  #!F-adobe-courier-bold-r-normal--18*   #!N # Time-Series Data

#!N 1. In the Data Prompter initial dialog box, select  #!F-adobe-times-bold-r-normal--18*   
Grid or Scattered File #!EF , select the leftmost button in 
the  #!F-adobe-times-bold-r-normal--18*   Grid type #!EF row (regular grid) and deactivate the 
 #!F-adobe-times-bold-r-normal--18*   Single time step #!EF toggle button. #!N #!I30 #!N 2. 
Confirm that the  #!F-adobe-times-bold-r-normal--18*   Block #!EF toggle button is activated and 
click on  #!F-adobe-times-bold-r-normal--18*   Describe Data #!EF . The  #!F-adobe-times-bold-r-normal--18*   Full prompter 
#!EF dialog box appears. (Because this example  #!F-adobe-times-medium-i-normal--18*   requires #!EF the 
full prompter, the simplified dialog box is not accessible.) #!N #!I30 
#!N 3. Enter the path name of the data file in 
the  #!F-adobe-times-bold-r-normal--18*   Data file #!EF field: #!CForestGreen #!N #!N  #!F-adobe-courier-bold-r-normal--18*   #!N 
/usr/lpp/dx/samples/data/record_series #!EF #!N #!N #!EC #!N #!I30 #!N 4. Activate the 
 #!F-adobe-times-bold-r-normal--18*   Header #!EF toggle button. #!N #!I30 #!N 5. Step 4 
also enables the  #!F-adobe-times-bold-r-normal--18*   # of bytes #!EF button to the 
right. Click on this button and select  #!F-adobe-times-bold-r-normal--18*   string marker #!EF 
. #!N #!I30 #!N 6. Enter "Time Step 1 \n" in 
the associated text field to  #!Rsvarx86 specify that the data file 
is to be read starting with the line after "Time Step 
1" (see Note). Alternatively, selecting  #!F-adobe-times-bold-r-normal--18*   # of lines #!EF and 
specifying the value "2" in the text field would produce the 
same result. Note: The new-line character "\n" must be included in 
the specification, and the spacing between it and the marker must 
match that in the data file (e.g., if "Time Step 1" 
and "\n" are separated by three spaces in the file, they 
must be separated by three spaces in the specification). This spacing 
is easily determined in the Data Browser by placing the cursor 
at each point and reading the corresponding offset value (see  #!Ldp618,dxall170 f Figure 18  #!EL  
). #!N #!N #!I30 #!N 7. Enter the value "5" in 
each of the first two  #!F-adobe-times-bold-r-normal--18*   Grid size #!EF fields. #!N 
#!I30 #!N 8. Activate the  #!F-adobe-times-bold-r-normal--18*   Series #!EF toggle button and 
specify the number of series members by entering the value "7" 
in the associated  #!F-adobe-times-bold-r-normal--18*   n #!EF field. (Leave the  #!F-adobe-times-bold-r-normal--18*   start 
#!EF and  #!F-adobe-times-bold-r-normal--18*   delta #!EF fields unchanged.) #!N #!I30 #!N 9. 
Activate the  #!F-adobe-times-bold-r-normal--18*   Series separator #!EF toggle button, select  #!F-adobe-times-bold-r-normal--18*   # 
of lines #!EF , and enter the value "1" in the 
associated text field. (When the Import module reads the data file, 
it will skip the lines "Time Step 2," "Time Step 3," 
and so on.) #!N #!I30 #!N 10. Change  #!F-adobe-times-bold-r-normal--18*   Dependency #!EF 
from "positions" to "connections." To confirm this change, click on  #!F-adobe-times-bold-r-normal--18*   
Modify #!EF at the bottom of the dialog box (note the 
instruction there). #!N #!I30 #!N 11. Repeat Example 1, Step 10 
(see  #!Lex1a,dxall116 s To save the header file  #!EL  ), to save the header file, which should look 
like: #!N #!I0 #!N #!EF #!N #!CForestGreen #!N #!N  #!F-adobe-courier-bold-r-normal--18*   #!N

as in this example, the  #!F-adobe-times-bold-r-normal--18*   interleaving #!EF keyword is not 
required (it defaults to record). However, when series data include vectors, 
this keyword must be included and the appropriate value specified. For
