AFNI program: 1dcat

Usage: 1dcat [-form option] 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.
The row-by-row concatenation of the columns included in these  
files is written to stdout.

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.
All files must have the same number of rows.
For help on -form's usage, see ccalc's help for the option of the same name.
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
