1dcat

Contents

• 1dcat

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'

OPTIONS:
--------
  -nonconst: Columns that are identically constant should be omitted
             from the output.

  -nonfixed: 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.

  -form FORM: Format of the numbers to be output.
              You can also substitute -form FORM with shortcuts such
              as -i, -f, or -c.
              For help on -form's usage, and its shortcut versions
              see ccalc's help for the option of the same name.

  -stack: Stack the columns of the resultant matrix in the output.

  -sel SEL: Apply the same column/row selection string to all 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

EXAMPLE:
--------
  Input file 1:
   1
   2
   3
   4
  Input file 2:
   5
   6
   7
   8

  1dcat data1.1D data2.1D > catout.1D
  Output file:
   1 5
   2 6
   3 7
   4 8
