binary
ooc_name binary ?tcl_channel?
This writes raw (binary) data to the file specified by
tcl_channel,
which defaults to stdout (standard output).
For example:
% set file [open y.tmp w] file4 % $y binary $file % close $file % set file [open y.tmp] file4 % [nap_get binary $file f64] all ::NAP::248-248 f64 MissingValue: NaN References: 0 Unit: (NULL) Dimension 0 Size: 5 Name: (NULL) Coordinate-variable: (NULL) Value: 0 0.25 1 2.25 4 % close $file
hdf
ooc_name hdf ?switches? filename sds
This writes data from the NAO to
an SDS named sds within an HDF file named filename.
switches can be:
-unlimited: Create sds with unlimited dimension 0
-coordinateVariable expr: boxed NAO which
specifies coordinate variables.
-datatype type: HDF datatype:
c8, i8, i16, i32, u8, u16, u32, f32
or
f64
-range float: HDF
valid_range
-scale float: HDF
scale_factor
-offset float: HDF
add_offset
-index expr: position within SDS where
data is to be written.
If
"-coordinateVariable expr"
is not specified then the coordinate variables
of the main NAO are used if these exist.
If
"-index expr"
is not specified then the coordinate variables
of the main NAO are used if these exist,
otherwise writing starts at the beginning of the SDS.
Example:
% [nap "3 .. 7"] hdf simple.hdf vec
% exec hdp dumpsds simple.hdf
File name: simple.hdf
Variable Name = vec
Index = 0
Type= 32-bit signed integer
Ref. = 2
Rank = 1
Number of attributes = 1
Dim0: Name=fakeDim0
Size = 5
Scale Type = number-type not set
Number of attributes = 0
Attr0: Name = _FillValue
Type = 32-bit signed integer
Count= 1
Value = -2147483648
Data :
3 4 5 6 7
netcdf
ooc_name netcdf ?switches? filename var
This writes data from the NAO to
a netCDF variable named var within
the netCDF file named filename.
switches can be:
-unlimited: Create variable with unlimited dimension 0
-coordinateVariable expr: boxed NAO which
specifies coordinate variables.
-datatype type: netCDF datatype:
c8, i16, i32, u8, f32
or
f64
-range float: netCDF
valid_range
-scale float: netCDF
scale_factor
-offset float: netCDF
add_offset
-index expr: position within netCDF variable
where data is to be written.
If
"-coordinateVariable expr"
is not specified then the coordinate variables
of the main NAO are used if these exist.
If
"-index expr"
is not specified then the coordinate variables
of the main NAO are used if these exist,
otherwise writing starts at the beginning of the netCDF variable.
Example:
% $y net sq.nc area -coordinateVariable "x // {3 6 9}"
::NAP::241-241
% exec ncdump sq.nc
netcdf sq {
dimensions:
x = 8 ;
variables:
double x(x) ;
double area(x) ;
area:_FillValue = nan ;
area:long_name = "areas of squares" ;
area:units = "seconds" ;
data:
x = 0, 0.5, 1, 1.5, 2, 3, 6, 9 ;
area = 0, 0.25, 1, 2.25, 4, nan, nan, nan ;
}
Note that the netCDF variable area is dimensioned to 8
(the shape of the
argument specified by the
-coordinateVariable
swap
ooc_name swap ?tcl_channel?
Method swap is like method binary, except that bytes are swapped.
This enables writing of data to be read on a machine with opposite byte-order within words.
