  The study of the structure of viruses by X-ray free-electron lasers (XFEL)
attracts more attention in recent decades. Such experiments are based on the
collection of two-dimensional diffraction patterns measured at the detector
after diffraction of femtosecond X-ray pulses on biological samples. In order
to prepare the experiment at the European XFEL we simulated the diffraction
data for the tick-borne encephalitis virus (TBEV) with different parameters and
identified their optimal values. Following necessary steps of a
well-established data processing pipeline, the structure of TBEV was obtained
and the efficiency of the used methods was demonstrated.
