Abstract
An NLO QCD analysis of the final HERMES data on pion multiplicities is presented and a new set
of pion fragmentation functions is extracted from the best fit to the data. We have studied the socalled
[x, z] and [Q
2
, z] presentations of their data, as given by HERMES, which, in principle, should
simply be two different ways of presenting the experimental data. We have based our extraction on
an excellent fit to the [Q
2
, z] presentation of the data.
