csf - copy structured file
csf in=in-file out=out-file
csf
copies a NEMO structured file. By using the item and select keyword items
can be selected by name and/or number. Note that items can currently only
be selected from the top level, items within a set can not be selected
this way; they are copied as a whole. This is likely to be improved at
a later stage. Automatic data-conversion can also be done. By default all
items are copied, and no data conversion is applied.
An overview of the
top level items that are present in a structured file can be obtained with
the following Unix pipe:
% tsf in_file | grep "^[a-z,A-Z]" | grep -v "^tes" | awk ’{print $2}’
Although structured files can always be read when they were created on
a byte swapped machine, csf can also be used to create a file in which
the bytes are not swapped.
The following parameters are recognized
in order; they may be given in any order if the keyword is also given. Use
--help to confirm this man page is up to date.
- in=in-file
- Input file, must
be in filestruct(5NEMO)
format [no default].
- out=out-file
- Output file, will
be in filestruct(5NEMO)
format [no default].
- item=item-list
- List of top level
items, separated by comma’s or spaces, to be copied. If none are provided,
all items are selected. Note that the item-list will be case sensitive. [default:
-blank-].
- select=select-list
- List of numbers (1 being the first) that are select
for copying, after the above mentioned item-name selection (from the item=
keyword) has been applied. If none are provided, all are copied. [default:
-blank-].
- convert=convert-list
- List of conversions to make, separated by comma’s
or spaces. Each conversion is of the format from2to, where both the from
and to part are any of: d (double), f (float), h (half precision) , l
(long), i (int) or s (short). [Default: -blank-].
Some of the conversions
in convert= are not supported or are in danger of loosing more than just
precision.
An image with too much data-history can be cut by only
copying the Image items:
% csf in=map1.ccd out=map2.ccd select=Image
Items can only be selected (select=) from the top level.
