Hi I am using this code...
TVD = TVD(2083:10150);
TWT = TWT(2083:10150);
IntVP = IntVP(2083:10150);
IntVS = IntVS(2083:10150);
RhoG = RhoG(2083:10150);
regtime = TWT(1):2:TWT(end); % Regularization of time (TWT) in sec.
% Interpolation of VP, VS, Rho with respect to regtime.
regvp = interp1(TWT, IntVP, regtime, 'linear', 'extrap');
regvs = interp1(TWT, IntVS, regtime, 'linear', 'extrap');
regrhoG = interp1(TWT, RhoG, regtime, 'linear', 'extrap');
regTVD = interp1(TWT, TVD, regtime, 'linear', 'extrap');
regtime=regtime/1000; % time in seconds
and facing this error. How can I fix it.

The error message tells you, that TWT does not contain unique values. It is impossible to gues, how you want to solve this problem, because this depends on the nature of your data.

Hi Jan
Ultimately, I want to use these data to compute say RPP as a function of angle of incident. After I will convolve RPP with wavelet and output (seismic gathers) will be plotted against regtime. So that's why I need regular time and all the other data regularized with respect to time interval.
