Ensemble superpose

[Yago52]

Hello again,

I think the ref argument in superpose is selecting the atom and not the frame/conformation to superpose the ensemble. So a code like this:

#dados anteriores
data = '09072024'
spike_close = parsePDB('6vxx', chain = 'A', subset = 'ca')
chdir('/home/ysilva/ownCloud/mestrado/estruturas para projeto/scripts/data_cov3d/ensemble_close_'+ data)
#chdir('/home/ysilva/ownCloud/mestrado/estruturas para projeto/scripts/data_cov3d/ensemble_close_05122023')
ensemble_all_close = loadEnsemble('ensemble_all_close.ens.npz')
pca_all_close = loadModel('close.pca.npz')
#anm_all_close = loadModel('close.anm.npz')
chdir('/home/ysilva/ownCloud/mestrado/estruturas para projeto/scripts/data_cov3d')
#chdir('/home/ysilva/ownCloud/mestrado/estruturas para projeto/scripts/data_cov3d')
#dados estrutura de referência

chdir('/home/ysilva/estruturas_anton/teste')
#chdir('C:/Users/yagos/estruturas anton/teste')
ref = parsePDB('chain_A_aligned.pdb')

#trajetoria 6vxx
#chain A
chain_A_ensemble = parseDCD('chain_A_aligned.dcd')
chain_A_ensemble.setCoords(ref)
chain_A_ensemble.setAtoms(ref)

#chain B
chain_B_ensemble = parseDCD('chain_B_aligned.dcd')
chain_B_ensemble.setCoords(ref)
chain_B_ensemble.setAtoms(ref)

#chain C
chain_C_ensemble = parseDCD('chain_C_aligned.dcd')
chain_C_ensemble.setCoords(ref)
chain_C_ensemble.setAtoms(ref)

anton_close_all = chain_A_ensemble + chain_B_ensemble + chain_C_ensemble

#TRajetoria 6vyb
#chain A
chain_A_ensemble_open = parseDCD('sarscov2-11021571_chainA_aligned.dcd')
chain_A_ensemble_open.setCoords(ref)
chain_A_ensemble_open.setAtoms(ref)

#chain B
chain_B_ensemble_open = parseDCD('sarscov2-11021571_chainB_aligned.dcd')
chain_B_ensemble_open.setCoords(ref)
chain_B_ensemble_open.setAtoms(ref)

#chain C
chain_C_ensemble_open = parseDCD('sarscov2-11021571_chainC_aligned.dcd')
chain_C_ensemble_open.setCoords(ref)
chain_C_ensemble_open.setAtoms(ref)

anton_open_all = chain_A_ensemble_open + chain_B_ensemble_open + chain_C_ensemble_open

anton_map_open = combineEnsembles(ensemble_all_close, anton_open_all, iterpose=False)
anton_map_open.superpose(ref=0)
anton_map_close = combineEnsembles(ensemble_all_close, anton_close_all, iterpose=False)
anton_map_close.superpose(ref=0)

The superpose uses the first atom and not the first frame.
