Hello,
I'm not positive what you mean by log file, but in
looking at '3dvolreg -help', the '-dfile dname' option
seems a likely candidate. That is where the 9 motion
parameters are saved, over time.
The output of '2dImReg -help' shows a similar option,
'-dprefix dname', though it seems that the 3 motion
parameters for this will get stored in separate files.
So if you were to use "2dImreg -dprefix MP ...", then
MP.dx, MP.dy and MP.psi would be output (where each
file contains the registration parameters, over time).
Please let me know if this is not what you were looking
for.
