  We extract two nonsinglet nucleon Parton Distribution Functions from lattice
QCD data for reduced Ioffe-time pseudodistributions. We perform such analysis
within the NNPDF framework, considering data coming from different lattice
ensembles and discussing in detail the treatment of the different source of
systematics involved in the fit. We introduce a recipe for taking care of
systematics and use it to perform our extraction of light-cone PDFs.
