Hello,
I'm trying to compute a surface for a CG pure POPC membrane. In pseudocode, the procedure I'm following looks like:
import MDAnalysis from memsurfer import Membrane u = MDAnalysis.Universe(pdb_file, xtc_file) frame = u.trajectory[-1] atoms = u.select_atoms('name PO4') bbox = np.zeros((2,3)) bbox[1,:] = frame.dimensions[:3] membrane = Membrane.compute(atoms.positions, atoms.resnames, bbox = bbox, periodic = True)
Which yields the following error
terminate called after throwing an instance of 'std::length_error' what(): cannot create std::vector larger than max_size()
It looks like it has something to do with the box dimensions (maybe?) but I have no Idea how to fix it.
I also tried computing a surface from a random distribution of points within the same bounds as my membrane, and get the same error.
Thank you very much in advance for your help!
The text was updated successfully, but these errors were encountered:
how large is the system? can you provide atoms.positions.shape ?
atoms.positions.shape
Sorry, something went wrong.
The array where I have the positions has a (5000, 3) shape
