Hey Rick -

Interesting. Any idea why omitting the bash looping construct, and just doing a single file, ie:

3dhistog whatever.nii | head -2 | tail -1

works? Is it just a race condition of some kind? I had assumed that stdout was not passed through the pipe until it was explicitly closed by the main process, so this is a definite learning moment. Thanks.
