changing a text file

[rona baron]

Hello all,

I have a text file which I want to open as an image. My problem is that
right now I have a list of one column of numbers.
I need to copy the first 32 numbers and paste them to the first raw etc'..
Can I manipulte the text file to the format I need?

Any advice is appreciated,

Thanks,
Rona

this is doable with grep

e.g. for integers , creating 3 numbers per row tab-delimited, you would search for:

(\d+)\r(\d+)\r(\d+)\r

and replace with:

\1\t\2\t\3\t\r

( your end of line character(s) may differ from \r)

grep can can run from a command line or in many text editors (I use it in textwrangler on Mac OS)

regards

Steve

Hi
This can also be done in python using numpy reshape function.

from numpy import *
a = array([float(line.strip()) for line in open("c:\image1d.txt")])
savetxt("c:\image2d.txt",a.reshape(-1,32), delimiter = "\t")

then use Import/Text Image...

Sincerely,
Jerome
