Hi --
In using the following commandline:
3drotate -prefix run1_volreg -dfile d_volreg run_1+orig
the resulting file has a number of zero-ed out subbricks (no data). The lines from the d_volreg file for 2 of the offending subbricks are:
164 -0.004 -0.002 -0.002 0.037 -0.031 -0.033 94.16 92.64
165 -0.004 0.003 -0.001 0.077 -0.031 0.018 95.23 91.16
We tried applying just these 2 transformations to other functional data, and got the same result - blank subbricks. We found this for afni version 2.51e and 2.40e (linux). These parameters aren't drastically different from any of the others in the d_volreg file. Across multiple subjects and runs, this is occurring sporadically, for maybe 2 or 3 bricks per 200 in a file.
Any thoughts on why this is occuring would be appreciated.
Thanks,
Alex
