  <dc:description>We present updated results of the measurement of the atmospheric neutrino flux with the MACRO detector at Gran Sasso, using three data sets spread in a large energy range. In the high energy range, the upgoing throughgoing muon data set is in favor of νμ →ντ  oscillation hypothesis with a probability of 36.6% against the 0.36% for the no oscillation hypothesis.In the low energy range, the two data set are also in favor to the oscillation hypothesis showing a large defict for IU events and a reduced defict for US+ID events, since only the US events ( |50% ) are expected to oscillate Assuming a νμ →ντ  oscillation scheme, the results suggest a large range of the parameter values centered around Dm2=0.0025 eV2, sin2 2q = 1.</dc:description>
