[Chimera-users] translation and rotation in MATLAB using transformation matrices from chimera

[Oleksiy Kovtun]

Dear all, 

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.

I found out that if I open the rotated map

and fit it again, it gives close to correct translation

matrix.

 

What's going wrong here? Does anyone have a

solution how to overlay 3D arrays in MATLAB using chimera-reported
transformation matrices?

 

Many

thanks,

Oleksiy
