<br>
Chimera does not output Euler angles. The "measure rotation"
command (e.g. me rot #0 #1) will report to the Reply Log the
relative position of two models as a 3 by 4 matrix (3 by 3
rotation plus a translation vector), and also reports as a
rotation about an axis through a specified point and shift along
that axis. Euler angles only would handle the rotation, not the
relative translation between two maps. We don't use them because
there is more than one convention defining Euler angles and we
haven't seen much need. What software do you want to use that
takes them as input?<br>

<div>Hi Elaine,<br>
</div>
Could I obtain euler angles after I rotate a single map to
some special orientation or save it as a MRC file (not in
the situation of fitting one map to another)?<br>
</div>
Thanks!<br>

Simply saving a map to a file after fitting will not save
its new orientation, because the map file formats do not
include rotation/translation information. However, you can
create a new map on the grid of another map by resampling.
For details, please see this section on "saving after
fitting":<br>

<br>
There is a "Transform Coordinates" tool (in menu under
Tools... Movement) with which you can apply Euler angles if
you already knew them, but the information above is probably
more relevant to your situation.<br>
I hope this helps,<br>
