Hi Catalina,

nDaySkip= 10 ; positive means there will be no overlap
                     

nDaySkip= -10 ; negative
                             ; if the window is 90, then the overlap
                             ; days 81-90

---
  nDayWin  = 96       ; Wheeler-Kiladis [WK] temporal window length (days)
  nDaySkip = -65      ; time (days) between temporal windows [segments]
                      ; negative means there will be overlapping 
temporal segments
In this case, the last 31 days will be overlapped

Hope all is well!
