    Hello,

    Is this a known bug or is there something wrong with my installation.

    Regards,

    Hi guys,

    Version 3+ marks a rewrite of the original program and unfortunately the region selection tool was never transferred over. I kept the icon in as a placeholder in case there was interest (seems like there is!). I'm not too active with this project anymore, but I'll certainly let the next generation of caretakers know - shouldn't be too hard to put back in.

    All the best,
    Paris

      Hi Paris,

      Thank you very much for the reply. The region selection tool having been left out of this version of the program makes me wonder if I am correct in thinking that it has an effect on what is sent to the optimizer. Is this tool for viewing only, or does it improve registration to remove any residual noise with it? Thanks again for your time and assistance.

      Best,
      Stephanie

        In the versions where the region selection tool is not diasbled the edited version of the edge-detected image will indeed be sent to the optimizer (as far as I know there are no bugs with this). If it seems like the optimizer is not taking in the correctly edited version definitely let me know - unfortunatley I can't double check this currently as I don't have access to a Windows machine today, but I'll see if I can get ahold of one in the coming days. However Version 3 is certainly much faster if you have a somewhat recent (last 2 years or so) Nvidia GPU, so I would still recommend using it.

        EDIT: A quick and dirty way of checking whether or not the image is being properly selected would be to run the optimizer at a small search frame (say 0 for all x, y, and all angles and then 1 in the z direction) and see what the function value is. Then edit the image to almost no lines and rerun the optimizer in the same position and see if there is any difference in the function value. If there is that should indicate that the edited image was sent to the optimizer.

        Good luck!
        Paris
