If you wanted to see the voxels common to two sets of activations, you could
use something like fslmaths <activation1> -bin <activation1_bin> ; fslmaths
<activation2> -bin <activation2_bin> ; fslmaths <activation1_bin> -add
<activation2_bin> -thr 2. This converts the activations to 1s, adds them
together, and then includes voxels only common to both (with a value of 2).
Peace,
Matt.

Subject: [FSL] masking procedure
Hello,
I'm beggining to use FSL and I would like to see common activations between
two conditions (and obtain an image with these activations).
I was thinking of doing it using masking procedures. How do I do this and
is there a better way to do it (rather than using masks)?
I've tried the pre-threshold masking in Feat but it doesn't do this.
Thanks.
Carlos
