I want to reconstruct the signal usign only the detail or either the approximation coefficents. is this possible?

yes, it is possible to reconstruct using only approximation coefficients or detail coefficient. have a look into appcoeff() or detcoeff(), there are also examples in the documentation.

@Jonas Hi I wanted to ask if you have any suggestion on how I coul reconstruct the approximations and details at all levels after using swt (undecimated discrete wavelet transform). Thanks!
