Thanks @ameyakhot !

This is a good step towards fixing the issue, but perhaps the issue wasn't clear enough, my bad!

This helps start with it, but now we need to do something with that groundtruth :)

This is related to the Quameasopts variable, that sets the quality measures options. As it is now, each iteration will check the quality measures against the previous iteration. The idea of adding a groundtruth is that when this is given (not otherwise), the quality measures should be compared against the groundtruth, instead of comparing them against the previous iteration.

I see. So for every iteration, if the Quameasopts variable needs to be compared to groundtruth (if given else None). What actions should be taken if they Quameasopts is equal to groundtruth? Can you share some details?

Thank you for your support.

hi @ameyakhot , no not the Quameasopts that is the options variable that is used to control that.

I would suggest having a quick look on how this variable is used in the code. You can also check the MATLAB code (e.g. SART.m) to see how MATLAB handles this.

Thank you for the explanation @AnderBiguri . I'll take a look for sure at the matlab and see how it works and try to understand what needs to be done in here.
