  In July 2018 an optimization run for the proposed charm cross section
measurement for SHiP was performed at the CERN SPS. A heavy, moving target
instrumented with nuclear emulsion films followed by a silicon pixel tracker
was installed in front of the Goliath magnet at the H4 proton beamline. Behind
the magnet, scintillating-fibre, drift-tube and RPC detectors were placed. The
purpose of this run was to validate the measurement's feasibility, to develop
the required analysis tools and fine-tune the detector layout. In this paper,
we present the track reconstruction in the pixel tracker and the track matching
with the moving emulsion detector. The pixel detector performed as expected and
it is shown that, after proper alignment, a vertex matching rate of 87 % is
achieved.
