Has any one done iterative reconvolution in Origin ?. ie, instead of deconvolving the signal from response, you convolve your response with a model so that you can reproduce the measured signal. Your model may depend on a set of parameters say, a_j, j = 1,..,N. You need to iteratively adjust a_j's and convolve with response so that you match your measured data (in a least square sense). I would appreciate any pointers how you can do this in Origin. Any one has
a code for this ?.

It can be done manually with a sample file "OriginLab\Samples\Programming\NAG FFT Convolution.OPJ". You also need to have "NAG FFT Convolution.C" in the same directory for it to work correctly. Then, copy your response function into columns A and C, and set column B to the function with your adjustable parameters.

The downside is that it has to be manually. I've been working on something similar for fluorescence decay times. I'll post the code if I can get it to work.
