We present a first preliminary determination of a set of collinear fragmentationfunctions of charged pions based on the NNPDF methodology. This determination isbased on a wide set of single-inclusive annihilation data, including the mostrecent and precise measurements from B-factory experiments. Our analysis isperformed at leading, next-to-leading and next-to-next-to-leading order inquantum chromodynamics. We discuss the result of our fits, highlighting thequality of their description of the data and their stability upon inclusion ofhigher-order corrections.
