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.

Hi,

Running match showmatrix true, gives two matrices. What's the difference between the two? I already saved the file after fitting it so it should have only one set of coordinates, its original coordinates?!

Regards
