Hi all,

This might be a naive question or I could be totally off track but I could not find a solution in the 3dcalc manual.
I'm trying to normalize the beta weights using the mean zero order baseline coefficient from 6 runs thus - ß*100/a0,
where a0 is the mean zero order baseline coefficient (across all 6 runs) from a 3dDeconvolve analysis.

I use 3dcalc to do this. I begin with a dataset (infile+orig) having dimensions 3.75x3.75x6.00 but the output file (outfile+orig) seems to have been resampled to 1.00x1.00x1.00 (or at least 3dinfo suggests so). Is there a way to suppress this resampling and keep the original voxel dimensions?

3dcalc \
-datum float \
-a2 infile+orig \
-b4 infile+orig \
-c6 infile+orig \
-d8 infile+orig \
-e10 infile+orig \
-f12 infile+orig \
-g14 infile+orig \
-expr 'g*100/((a+b+c+d+e+f/6))' \
-prefix outfile


Thanks for your help.
