Create

Jump to navigation Jump to search

create creates a new molecule object from a selection. It can also be used to create states in an existing object.

USAGE

create name, (selection) [, source_state [, target_state ]]
  • name = object to create (or modify)
  • selection = atoms to include in the new object
  • source_state (default: 0 - copy all states)
  • target_state = int: -1 appends after last state {default: 0}

PYMOL API

cmd.create(string name, string selection, int source_state, int target_state,int discrete)

NOTES

If the source and target states are zero (default), all states will be copied. Otherwise, only the indicated states will be copied.

Target state -1 will append new states.

EXAMPLES

# merging two multi-state objects with the create command
# obj1 has 25 states and obj2 has 40 states 

load multi_state_obj1, obj1
load multi_state_obj2, obj2

# merge the two multi-state objects back to back into obj3
# 0 indicates every states from obj1 should be included
# 1 indicates that the first state of obj3 is the first state from obj1 etc.

create obj3, obj1, 0, 1

# as obj1 has 25 states, the first state of obj2 must be state 26 to create a multi-state object of obj1 and obj2 back-to-back 
# 26 indicates that the 26th state of obj3 is state nr. 1 of obj2 etc. 

create obj3, obj2, 0, 26

# Obj3 now has 65 states (25 from obj1 and 40 from obj2)
# save obj3 as a multi-state pdb file
# use state=0 to get all states into one pdb file

save obj3.pdb, obj3, state=0
