AFNI program: 1dcat
Output of -help
Usage: 1dcat [options] a.1D b.1D ...
where each file a.1D, b.1D, etc. is a 1D file.
In the simplest form, a 1D file is an ASCII file of numbers
arranged in rows and columns.
1dcat takes as input one or more 1D files, and writes out a 1D file
containing the side-by-side concatenation of all or a subset of the
columns from the input files.
* Output goes to stdout (the screen); redirect (e.g., '>') to save elsewhere.
* All files MUST have the same number of rows!
* Any header lines (i.e., lines that start with '#') will be lost.
* For generic 1D file usage help and information, see '1dplot -help'
The '-nonconst' option indicates that columns that are identically
constant should be omitted from the output.
The '-nonfixed' option indicates to keep only columns that are
marked as 'free' in the 3dAllineate header from '-1Dparam_save'.
If there is no such header, all columns are kept.
The '-form' option indicates the format of the numbers to be output.
For help on -form's usage, see ccalc's help for the option of the same name.
The '-sel SEL' options allows you to apply the same column/row selection
string to all of the filenames on the command line.
For example 1dcat -sel '[0,2]' f1.1D f2.1D
is the same as: 1dcat f1.1D'[1,2]' f2.1D'[1,2]'
the advantage of the option is that it allows wildcard use
in file specification so that you can run something like:
1dcat -sel '[0,2]' f?.1D
Input file 1:
Input file 2:
1dcat data1.1D data2.1D > catout.1D
