Hi!

It is a quite simple question, but I do not have any idea, how I can do that.
I want to write out TT-co-ordinates and z-scores of local maxima of a functional dataset, which is already converted to z-score( zsc+tlrc).
After using 3dExtrema I get a dataset ext+tlrc containing 1s on locations, where the program found local maxima.
I thought I could just multiply these datsets:
3dcalc -a ext+tlrc -b zsc+tlrc -expr "a*b" -prefix zext
and write the dataset out in a text file:
3dmaskdump -noijk -xyz -mask ext+tlrc -o table zext+tlrc

However, I get an output like this:
47 124 16 2

However, the fourth number should be the voxel value, if I understood the program right. But it is always an integer.... and no z-score..

Does anybody know, what I have missed ?
