[Chimera-users] how to get translation and rotation vectors for move and turn commands

[Elaine Meng]

Hi Jan,
I don't understand what you are doing,  thus I'm not sure if any of the following will help, but "matrixcopy" will apply the transformation of one model to another.  Or you can write a model's transformation matrix to a file with "matrixget" and apply a transformation matrix from a file to a model with "matrixset."
