RMS is root-mean-square of the difference between the intensities of
target volume and the indexed volume. The 10th is the vector motion of
the center of rotation with respect to the target image (ie, before
correction).

Hi all,
I'm analyzing some motion data and I had a two quick questions about
the last two columns of the fmc.mcdat file. According to the wiki,
the 9th column is RMS error after correction. Could someone shed some
light on what RMS stands for and how it's useful? Also, the 10th
column is the total vector motion in mm...is this total before or
after motion correction?
Thanks in advance!
