This can be quite easy, since the six motion parameters are installed in six
Say, the motion file is rpxxx.txt. In matlab, load rpxxx.txt; plot(rpxxx). OK.
if you have several runs, say, run 1~3, motion files are rp1.txt, rp2.txt,
in matlab, load rp1.txt; load rp2.txt; load rp3.txt; plot([rp1;rp2;rp3]). OK.
