We study the effects of non-standard interactions on the oscillation pattern of atmospheric neutrinos. We use neutrino oscillograms as our main tool to infer the role of non-standard interactions (NSI) parameters at the probability level in the energy range, E ∈ [1,20] GeV and zenith angle range, cosθ∈ [-1,0]. We compute the event rates for atmospheric neutrino events in presence of NSI parameters in the energy range E ∈ [1,10] GeV for two different detector configurations - a magnetized iron
