Matrix Copy

Matrix_copy copies the object matrix from one object to another.

This command is often used after a protein structure alignment to bring other related objects into the same frame of reference.


matrix_copy source_name, target_name


  • source_name = string: name of object to take matrix from
  • target_name = string: name(s) of object(s) to copy matrix to
  • source_mode = integer: 0: raw coordinates, 1: object TTT matrix, 2: state matrix, 3: camera matrix transformation {default: -1: matrix_mode setting}
  • target_mode = integer: (see source_mode)
  • source_state = integer: object state {default: 1}
  • target_state = integer: object state {default: 1}
  • target_undo = 1/0: ??? {default: 1}


Here's a practical example. We grab two proteins and their density maps. We then align one to the other and then use matrix_copy to move over the density map:

<source lang="python">

  1. fetch two proteins and their maps

fetch 1rx1 3dau, async=0 fetch 1rx1 ..→
