creating txt files

Naomi Barth
For my research I need to convert a set of 8-bit images into txt files.  The
stack of images make up a three dimensional image, there are about 150
images per stack.   I have a program that will read read this txt file and
do 2-pt statistics on the set.  Because I am dealing with so many large
images in each data set, It would take my program too long to open up 150
txt files.  So my question is does any one know how to turn a stack of
images into a single txt file, that I will be able to tell the difference
between the x, y, and z pixels.  If not, does anyone know how to turn a
bunch of images into txt files at once, so I don't have to do that by hand.

Thank you
-Naomi

Naomi,

do you need 2-point statistics of the volume (stack) or of each of
the stack's images?

If the latter is what you need, why not compute the 2-point
statistics of every image in ImageJ? For instance, you may use the
autocorrelation function of every image which in fact is the
histogram of all 2-point products.

I need the 2-pt stats of the whole stack.  I will need  to correlate pts
from one image to pts in another

Re: creating txt files

You can use a simple macro to save the images in a stack into txt  
files, something like this:

for (i=0; i<nSlices;i++){
        setSlice(i+1);
        saveAs("Text Image","/Path...///Stack"+i+".txt");
}
change the Path...// into the path where your images will be saved.
