 #!F-adobe-times-bold-r-normal--18*   Data file #!EF #!I50 #!N The first information the General 
Array Importer requires is the path name of the data file 
to be imported. This name can be entered directly in the 
text field to the right of the  #!F-adobe-times-bold-r-normal--18*   Data file #!EF 
label. Alternatively, you can click on the ellipsis button (  #!F-adobe-times-bold-r-normal--18*   
... #!EF ) to the right of the text field. If 
you select  #!F-adobe-times-bold-r-normal--18*   File Selection Dialog... #!EF from the pop-up menu, 
you can select a file from the dialog list. Note that 
using the  #!F-adobe-times-bold-r-normal--18*   File Selection #!EF dialog list is simply a 
shortcut for typing in the path name. The  #!F-adobe-times-bold-r-normal--18*   Browser #!EF 
option on the ellipsis pop-up is discussed in  #!Lbrowse,dxall169 h Data Prompter Browser  #!EL  . #!N

 #!Rdprhdr #!I50 #!N If your data file has a header (an 
initial section that must not be imported with the data), activate 
the  #!F-adobe-times-bold-r-normal--18*   Header #!EF toggle button. Clicking on the button immediately 
to the right of the toggle will generate a pop-up menu 
of three options for specifying where the header stops and the 
data begins: #!N #!I0 #!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 #!N o 
 #!F-adobe-times-bold-r-normal--18*   # of bytes #!EF (from the beginning of the file) 
#!N #!I30 #!N o  #!F-adobe-times-bold-r-normal--18*   # of lines #!EF (from the 
top of the file) #!N #!I30 #!N o  #!F-adobe-times-bold-r-normal--18*   string marker 
#!EF #!N #!I0 #!N #!EF #!N Click on one and enter 
the appropriate information in the associated text field to the right. 
The appropriate offset or string can be determined by browsing the 
data file. (See Notes in  #!Lhdrkwd,dxall147 h header  #!EL  . As earlier examples demonstrate, 
this information ultimately appears in a  #!F-adobe-times-bold-r-normal--18*   header #!EF keyword statement 
in a header file.) #!N #!N See also  #!Lhdrkwd,dxall147 h header  #!EL  . #!N

#!N Located below the  #!F-adobe-times-bold-r-normal--18*   Header #!EF toggle button are two 
buttons labeled  #!F-adobe-times-bold-r-normal--18*   Grid Size #!EF and  #!F-adobe-times-bold-r-normal--18*   # of Points 
#!EF . #!N #!N If the data has connections that are 
gridded, click on the  #!F-adobe-times-bold-r-normal--18*   Grid size #!EF button. Specify the 
dimensions of the grid in the associated text fields (e.g., if 
the data are 2-dimensional, enter the sizes in the first two 
fields and leave the last two blank). #!N #!N If the 
data consist of unconnected points, click on the  #!F-adobe-times-bold-r-normal--18*   # of 
Points #!EF associated button, and enter the appropriate number in the 
associated text field. #!N #!N Notice that these choices affect other 
aspects of the Data Prompter. The choice of points deactivates the 
 #!F-adobe-times-bold-r-normal--18*   Data order #!EF buttons and all but the first origin-delta 
field in the  #!F-adobe-times-bold-r-normal--18*   Positions #!EF section at the bottom. #!N

Data Format #!EF #!I50 #!N The format of the data can 
be ASCII/Text or Binary/IEEE. The selection of  #!F-adobe-times-bold-r-normal--18*   Binary/IEEE #!EF ) 
activates the  #!F-adobe-times-bold-r-normal--18*   Significant Byte First #!EF option button immediately to 
the right. You may then select Most Significant Byte First (MSB) 
or Least Significant Byte First (LSB). For ASCII (or Text) format, 
this option button is inactivated. #!N #!N See also  #!Lformkwd,dxall146 h format  #!EL  . 
#!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   Data Order #!EF #!I50 #!N This option 
specifies the layout of multidimensional arrays.  #!F-adobe-times-bold-r-normal--18*   Row #!EF (majority) means 
that the last index of a multidimensional array varies fastest (as 
in C language).  #!F-adobe-times-bold-r-normal--18*   Column #!EF (majority) means that the first 
index varies fastest (as in FORTRAN). #!N #!N See also  #!Lmajkwd,dxall150 h majority  #!EL  
. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   Field Interleaving #!EF #!I50 #!N The 
data to be visualized must be organized in one of two 
general styles: block or columnar. For data laid out in blocks, 
select  #!F-adobe-times-bold-r-normal--18*   Block #!EF from the  #!F-adobe-times-bold-r-normal--18*   Field Interleaving #!EF option 
menu. For columnar style, select  #!F-adobe-times-bold-r-normal--18*   Columnar #!EF . #!N #!N 
Note that when  #!F-adobe-times-bold-r-normal--18*   Columnar #!EF is selected, both  #!F-adobe-times-bold-r-normal--18*   Vector 
Interleaving #!EF and  #!F-adobe-times-bold-r-normal--18*   Series Interleaving #!EF are grayed out. (See 
 #!Lgaints,dxall113 h Some Notes on General Array Importer Format  #!EL  for more information about the block and columnar styles.) #!N

#!EF #!I50 #!N The interpretation of vector data organized in records 
(blocks) is specified by the  #!F-adobe-times-bold-r-normal--18*   Vector Interleaving #!EF option button. 
The two choices in the associated option menu are: #!N X[0]Y[0], 
X[1]Y[1],..., X[n]Y[n] "Vectors together" and X[0], X[1],..., X[n], Y[0], Y[1],..., Y[n] 
"Components together" #!N #!N "Vectors together" means that all of the 
components of one vector are written together, then all the components 
of the next vector, and so on. "Components together" means that 
all of the x-components are written together, then all the y-components, 
and so on. #!N #!N See also  #!Lintrkwd,dxall148 h interleaving  #!EL  . #!N #!I0 
#!N  #!F-adobe-times-bold-r-normal--18*   Series #!EF #!I50 #!N For data consisting of a 
sequence of fields, click on the  #!F-adobe-times-bold-r-normal--18*   Series #!EF toggle button, 
activating the three text fields to the right: #!N #!I0 #!N 
 #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 #!N o  #!F-adobe-times-bold-r-normal--18*   n #!EF specifies the 
number of series members in the data file. #!N #!I30 #!N 
o  #!F-adobe-times-bold-r-normal--18*   start #!EF specifies the series value for the first 
series member. #!N #!I30 #!N o  #!F-adobe-times-bold-r-normal--18*   delta #!EF specifies the 
difference in position between successive series members. #!N #!I0 #!N #!EF

Series Interleaving #!EF #!I50 #!N Activating the  #!F-adobe-times-bold-r-normal--18*   Series #!EF toggle 
button also activates the  #!F-adobe-times-bold-r-normal--18*   Series Interleaving #!EF option menu if 
 #!F-adobe-times-bold-r-normal--18*   Field Interleaving #!EF is set to  #!F-adobe-times-bold-r-normal--18*   Record #!EF . 
The option menu contains two choices: #!N F1(s0), F2(s0), F1(s1), F2(s1),..., 
F1(sn), F2(sn) "Series members together" #!N and #!N F1(s0), F1(s1), F2(s0), 
F2(s1),..., Fn(s0), Fn(s1) "Fields together" #!N #!N This feature is useful 
for series that consist of more than one field. "Series members 
together" means that the data for each field of series member 
zero (s0) are followed by all the data for each field 
for series member one (s1), and so on. "Fields together" means 
that all the series members for field 1 (F1) are followed 
by all the series members for field 2 (F2), and so 
on. #!N #!N See also  #!Lintrkwd,dxall148 h interleaving  #!EL  . #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   
Series Separator #!EF #!I50 #!N This feature is required only if 
the data for series members are separated from one another by 
non-data (e.g., comments). The specification is identical to that of the 
 #!F-adobe-times-bold-r-normal--18*   Header #!EF keyword (see  #!Ldprhdr,dxall167 s Header  #!EL  ). #!N #!N See also 
 #!Lserskwd,dxall152 h series  #!EL  . #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   Grid Positions #!EF #!I50 #!N 
This feature is required for gridded data if you have not 
specified that the positions are stored in the file (by naming 
one of the fields with the reserved word "locations"). #!N #!N 
The entire section is grayed out if the "locations" reserved word 
is used. If the data consist of unconnected points (and are 
so specified in the initial dialog box or by the  #!F-adobe-times-bold-r-normal--18*   
# of points #!EF toggle), all but one of the origin-delta 
fields is grayed out. See also  #!Lposkwd,dxall155 h positions  #!EL  . #!N #!N The 
option button just to the right of the  #!F-adobe-times-bold-r-normal--18*   Grid positions 
#!EF (or  #!F-adobe-times-bold-r-normal--18*   Point positions #!EF ) title offers the following 
choices: #!N #!I0 #!N #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   Completely regular 
#!EF #!EF #!I50 #!N The dimensions of the grid are all 
regular. This selection fixes the regular/irregular option button to the left 
of each dimension field at "regular" (i.e., "irregular" cannot be selected 
for any dimension). There will be as many origin/delta fields enabled 
as there are dimensions as specified by  #!F-adobe-times-bold-r-normal--18*   Grid size #!EF 
, or one if  #!F-adobe-times-bold-r-normal--18*   # of Points #!EF is chosen. 
#!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   Partially regular #!EF #!EF #!I50 #!N 
Each dimension of the grid can be either regular or irregular. 
This selection specifies a product of arrays. Thus, for example, the 
grid may be spaced equally in one dimension, but have an 
explicit list of positions in another dimension. For each dimension, you 
can set the  #!F-adobe-times-bold-r-normal--18*   regular #!EF /  #!F-adobe-times-bold-r-normal--18*   irregular #!EF option 
menu to the appropriate choice, and then enter either the origin, 
delta pair for that dimension or the explicit list of positions 
for that dimension. #!N #!N #!I0 #!N Notes: #!N #!I30 #!N 
1. A regular dimension is specified completely by an origin and 
a delta (the number of positions in the dimension is specified 
in the grid section). #!N #!I30 #!N 2. Specification of an 
irregular dimension requires an explicit and complete list of values (the 
number of items in the list must exactly equal the number 
of positions in the dimension). #!I0 #!N #!N #!N #!I0 #!N 
 #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   Explicit position list #!EF #!EF #!I50 #!N The positions 
are completely irregular and must be explicitly specified. If this option 
is chosen, then a single field is enabled for you to 
enter the position list. The number of items in the list 
should be equal to the total number of positions x the 
dimensionality of the positions. #!I0 #!N #!N #!I0 #!N #!N #!N
