Strange effect on ReOh and ALFF maps

Submitted by dbd18 on
Dear experts, I am trying to compute ALFF and ReOH maps with DPARSFA (for parameters of ReOh calculation, see attached document. In case of ALFF I have only smoothed before and leave all the rest the same). The pipeline runs smoothly but I got a strange effect on the resulting maps (see attached figure). Could you please advice on what to do? Thank you very much in advance, Kind regards, Bianca
