I'm sorry my explanations were not clear.

The executable command takes the columns of file specified in argument 1 (infile1) and adds them to the file specified in argument 2 (infile2). It creates a new file that starts with columns from infile2, followed by columns from infile1. So, the first command line is:

combining.executable infile1 infile2 > outfile1

This will take infile2 as the basis and add columns to it from infile1. The outfile1 will start with columns from infile2 and finish with columns from infile1.

The we run the following command:

combining.executable infile3 outfile1 > outfile2

This will take the columns from the file specified as argument 1 (infile3) and add them to the file specified in the argument 2 (outfile1). It is the same procedure as in step1, so the program does the same thing, nothing changes. The resulting outfile2 will start with columns from outfile1 and finish with columns from infile3. So, all 3 files are combined and nothing is deleted/replaced.

For the next step, we'll need outfile2 and infile4. So, we can delete the outfile1 as its info is now in outfile2. And so on...

This is your next question:

What is the format of the real names of your input files? (Please show us the actual names of your 1st input file and your last input file.)

The answer: the files are simple text files, here is the name of my first input file:

9464294024_R01C01header

and the last file name is:

9479475073_R12C02header

here is a small subsample of the files:

Code:

9464294024_R01C01header  9477371149_R12C02header  9477871078_R06C01header  9477875165_R03C01header  9477885102_R05C01header  9479475073_R10C02header
9464294024_R01C02header  9477371157_R01C01header  9477871078_R06C02header  9477875165_R03C02header  9477885102_R05C02header  9479475073_R11C01header

Next question: And, is the number of input files a constant?

I'm not sure I understand this question. There is exactly 5427 files than need to be combined into one.

Next question: And, what name do you really want for your output file?

The name of the output file does not really matter for me. It can be anything as long as it contains the columns of all the 5427 files combined into one text file.

Many thanks!

mwrap

MWRAP(1)							   MWRAP manpage							  MWRAP(1)

NAME

       mwrap - Octave/MATLAB mex generator

SYNOPSIS

       mwrap [-mex outputmex] [-m output.m] [-c outputmex.c] [-mb] [-list] [-catch] [-c99complex] [-cppcomplex] infile1 infile2 ...

DESCRIPTION

       mwrap is an interface generation system in the spirit of SWIG or matwrap.  From a set of augmented Octave/MATLAB script files, mwrap will
       generate a MEX gateway to desired C/C++ function calls and .m function files to access that gateway.  The details of converting to and from
       Octave's or MATLAB's data structures, and of allocating and freeing temporary storage, are hidden from the user.

OPTIONS

       -mex   specifies the name of the MEX function that the generated functions will call.  This name will generally be the same as the prefix
	      for the C/C++ output file name.

       -m     specifies the name of the Octave/MATLAB script to be generated.

       -c     specifies the name of the C MEX file to be generated.  The MEX file may contain stubs corresponding to several different generated
	      files.

       -mb    redirect Octave/MATLAB function output to files named in the input.  In this mode, the processor will change Octave/MATLAB function
	      output files whenever it encounters a line beginning with @.  If @ occurs alone on a line, the output will be turned off; if the
	      line begins with @function, the line will be treated as the first line of a function, and the m-file name will be deduced from the
	      function name; and otherwise, the characters after @ (up to the next set of white space) will be treated as a filename, and mwrap
	      will try to write to that file.

       -list  print to the standard output the names of all files that would be generated from redirect output by the -mb flag.

       -catch surround library calls in try/catch blocks in order to intercept C++ exceptions.

       -c99complex
	      use the C99 complex floating point types as the default dcomplex and fcomplex types.

       -cppcomplex
	      use the C++ complex floating point types as the default dcomplex and fcomplex types.
