Hi Dorit,

Yes, adding 1 to the seed is properly done via: @ seed = $seed + 1 .

However, you still need to access it via $seed, not @seed. The '@'
command is basically the same as 'set', except that it is computational.
So the script should contain "-seed $seed".

The make_random_timing.py program should be in the same directory as
3dDeconvolve, and they should both be executable (i.e. if you run
"ls -l make_random_timing.py 3dDeconvolve", there should be 'x' markers
in the permissions area.

Maybe you simply need to run 'rehash', I don't know.

---

In any case, you will need to fix the application of $seed and re-run
the script. 50000 should be more than enough iterations otherwise.
