7.1.6. 1dFlagMotionΒΆ

Link to classic view

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.
