Hi Gang,

3dcalc script in nedit:

3dcalc -a stats.xxxxxxx_20140102.mid2_REML+tlrc -b stats.xxxxxxx_20140109.mid2_REML+tlrc \
-expr 'abs(a-b)' \
-prefix xxxxxxx_absMid2 \


3dinfo dset a:

There are 183 sub-bricks for dsetA, and 153 sub-bricks for dsetB that I did not paste. Is it a problem to have a different number of sub-bricks? I also see an issue with size...3dinfo is helpful! Number of values stored for each pixel and statpar values are different between dsets.

You are amazing!!! THANK YOU.

Lindsay
