[Chimera-users] report rotate and shift value in MatchMaker

[Elaine Meng]

Hi Yanhe,
The matrix just includes the total shift and total rotation of one model relative to another... there is nothing like iteration.   What the matrix means is explained in the "measure rotation" help:
<https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/measure.html#rotation>

In the Log, the shift is also given in a second way, as an axis (which can be pointed in any direction) and the total shift along that axis. 

I hope this helps,
Elaine
