I have a signal and applied a filter by using filter function in matlab (the built in filter function of matlab). I added padding to my data. now my filtered signal has a shift equal to the padd compared to the initial signal ( I should mention I added padding to the initial signal too). The final output of the filter is equal to the input signal but I dont know where these shift in the signal is arising from. I added a screenshot of the initial and filterd signal. the blue channel is the initial signal and the orange one is the filtered signal.
