[Chimera-users] Match showmatrix true motion in original coordinates

[Elaine Meng]

Hi Ahmad,
It sounds like before you used this match command, earlier in the session you had already moved #76 separately from #2.  So the first matrix is just the change in position of #76 from this one match command, whereas the second matrix has all of its position changes (in the whole session since file opening) relative to #2.
Regards,
Elaine
