Hi all,

I've got a spearman's correlation file generated by 3dfim+, which I then use in a 3dcalc command as follows

3dcalc -a grey_thr2.1_s2.5_tstat1.0.95thresholded.ordered.nii.gz -b sp+tlrc.HEAD -expr "step(a)*b" -prefix killme1

However, the output of this command (killme1) looses its statcode = fico, so I tried to add it back in (I'd like the p-value to be available in the afni window) with 3drefit as follows

3drefit -fico killme1+tlrc.HEAD
but it reports

++ 3drefit: AFNI version=AFNI_2008_07_18_1710 (Jul 23 2008) [64-bit]
++ Authored by: RW Cox
++ Processing AFNI dataset killme1+tlrc.HEAD
** ERROR: Can't change dataset to new type:
* mismatch in number of sub-bricks!
*+ WARNING: Over-writing dataset ./killme1+tlrc.BRIK
++ 3drefit processed 1 datasets

I tried adding the -statpar argument to 3drefit but it made no difference, 3drefit still complains.

3dinfo on the two brik files provided to 3dcalc reports the following:

Does anyone know why 3drefit will not do what I want?
