Hi Julio, The matrixget command gives the placement of the map in Chimera world coordinates. If you simply shift or rotate the map with the mouse this changes. That is not what you want. You want the placement of the map that was fit relative to the map it was fit into. That is what the Fit in Map dialog reports in the Reply Log. Use that. For transformations expressed at 3 by 4 matrices Chimera does the rotation first (about 0,0,0) then the translation. Tom
Hi,
I am doing fitting of two maps and am getting different values of the transformation parameters: the ones given in the window where I specify the options (these seem to be correct), and those given by using the command "matrixget" --- these give a very large translation vector, and moreover, I don't see any relation between that vector and the correct translation.
Also, could you tell me what is the order used in Chimera: rotation, then translation? or translation, then rotation?
Thank you very much.
