<p>Dear all, </p><p>I need to merge two maps in MATLAB using
alignment data from chimera. Inputs: two maps of the same box size,
origin. I use matrixget - to report translation and rotation
matrices for the aligned map . Translation operation works well when
transferred into MATLAB (briefly, translation matrix gets converted in
eulers and pased on to tom_rotate command in MATLAB, TOM package). However
the x y z translation coordinates (the fourth column top to bottom in
matrixget - output) are way off the real translation when using tom_shift
command in MATLAB, TOM.</p><p>I found out that if I open the rotated map
and fit it again, it gives close to correct translation
matrix.</p><p> </p><p>What's going wrong here? Does anyone have a
solution how to overlay 3D arrays in MATLAB using chimera-reported
transformation matrices?</p><p> </p><p>Many
thanks,</p><p>Oleksiy </p><p> <br />
