Hi AFNI experts,

I just downloaded AFNI 64 bit for Mac OS and installed it on a new machine [compile date 11 Dec 2008]. However running the align_epi_anat.py gives me the following error with 3dAllineate:

========== Applying transformation to 168 sub-bricks ==========
++ ========== sub-brick #0 ==========
++ using -1Dmatrix_apply
++ Computing output image
*+ WARNING: sr907_bcrun_01_tlrc_bigal_raw+tlrc[0] scale to shorts misfit = 3.45% -- * Caution
++ Consider writing datasets out in float format.

(and shows this for every functional volume.)

Running the same command on exactly the same machine that runs the 'standard' (32 bit) version does not show this error [Compile date 5 November 2008]. Any ideas? Does it have to do with the 64 bit version? Should I floatize the data with to3d?

thank you,

Nick
