Hi, It would be good to make this more general so that it can be used elsewhere in the future. I would suggest maybe the following. We have a number of equations for an exponential:
1) b*e^(a.t) 2) b*e^(-a.t) 3) -b*e^(a.t) 4) -b*e^(-a.t) 5) c + b*e^(a.t) 6) c + b*e^(-a.t) 7) c - b*e^(a.t) 8) c - b*e^(-a.t) For the inversion recovery we use 8) and for the normal Rx we use 2). So maybe we could have a series of these functions, all of which are very similar. They could be called: 1) exp_2param 2) exp_2param_neg 1) exp_2param_inv 2) exp_2param_inv_neg 5) exp_3param 6) exp_3param_neg 7) exp_3param_inv 8) exp_3param_inv_neg These would be incredibly easy to add by simple code duplication (this is the fastest way computationally). What do you think? Cheers, Edward On 16 June 2011 12:24, Sébastien Morin <[email protected]> wrote: > Hi Ed, > > If you wish, yes, I could merge the files...
