ACKNOWLEDGMENTS
We thank G. M. Stewart from SLAC National Accelerator Laboratory for
assistance in making Fig. 1A. M.G. serves on the Science Advisory
Committee of LCLS, which manages the SLAC UED facility.Funding:
The experimental part of this research was performed at SLAC
MeV-UED, which is supported in part by the U.S. Department of Energy,
Office of Science, Office of Basic Energy Sciences (DOE BES) SUF
Division Accelerator & Detector R&D program, the LCLS facility, and
SLAC under contract nos. DE-AC02-05-CH11231 and DE-AC02-
76SF00515. T.J.M., T.J.A.W., X.Z., J.K.Y., and R.M.P. were supported by
the AMOS program within the Chemical Sciences, Geosciences, and
Biosciences Division of the DOE BES. M.G. and M.N. are funded via a
Lichtenberg Professorship of the Volkswagen Foundation. J.P.F.N.,
B.M., and M.C. were supported by the DOE BES under award no.
DE-SC0014170. Y.L. and T.W. were supported by the DOE under
award no. DE-FG02-08ER15984.Author contributions:J.Y., J.P.F.N,
T.J.A.W., Y.L., R.L., S.P., X.S., S.W., T.W., and X.W. carried out the
experiments. J.P.F.N., M.N., M.C., and M.G. improved the experimental
system. J.P.F.N., B.M., and M.C. tested the sample delivery system. J.Y.
analyzed the experimental data and performed the genetic structural
retrieval algorithm. X.Z. and T.J.M. performed the GAIMS simulation.

X.Z., R.M.P., and T.J.M. developed the computational method for AIED
simulation. X.Z., J.K.Y., and T.J.M. carried out the AIED simulation.
J.Y., X.Z., M.G, T.J.M., and X.W. prepared the manuscript, with
discussion and improvements from all authors.Competing interests:
None declared.Data and materials availability:All data underlying
the figures are deposited at Zenodo ( 34 ). The raw experimental
data are archived at the SLAC MeV-UED facility, and the raw
simulated data are stored at the Martinez laboratory at Stanford
University and SLAC. All data needed to evaluate the conclusions in
the paper are present in the paper or the supplementary materials.
