Dear experts,

I have several questions regarding "reposition surface" tool in freeview (V6beta):

1. Are here any documentation how to use "reposition surface" tool? I would especially velcome the explanation of significance of "sigma", "size" and "gradient direction" parameter. I tried to play with the parameters by trial and error, but I could not get satisfactory results.

2. It seems to me that the selection of the active volume (i.e. the volume according to that the surface is repositioned) does not reflect the currently highlighted volume. It seems to always use the volume on top of the list of the volumes, but I am not sure given the unpredictive behaviour of this tool I got so far.

3. It would be maybe handy to include special flag to recon-all to rerun remaining recon-all pipeline after the reposition of the surface in freeview have been used. What do you think?

4. Do you think there is a chance to implement recon-all to preserve part of the surface which has been repositioned by this tool in case of recon-all rerun (similarly like it is done with other edits)?

Regards,

Antonin Skoch
