AFNI program: 1dFlagMotion
Output of -help
Usage: 1dFlagMotion [options] MotionParamsFile
Produces an list of time points that have more than a
user specified amount of motion relative to the previous
time point.
Options:
-MaxTrans maximum translation allowed in any direction
[defaults to 1.5mm]
-MaxRot maximum rotation allowed in any direction
[defaults to 1.25 degrees]
** The input file must have EXACTLY 6 columns of input, in the order:
roll pitch yaw delta-SI delta-LR delta-AP
(angles in degrees first, then translations in mm)
** The program does NOT accept column '[...]' selectors on the input
file name, or comments in the file itself. As a palliative, if the
input file name is '-', then the input numbers are read from stdin,
so you could do something like the following:
1dcat mfile.1D'[1..6]' | 1dFlagMotion -
e.g., to work with the output from 3dvolreg's '-dfile' option
(where the first column is just the time index).
** The output is in a 1D format, with comments on '#' comment lines,
and the list of points exceeding the motion bounds listed being
intercalated on normal (non-comment) lines.
