Export crosshair position from MRI viewer to Matlab/ smooth display MRI viewer

[mheers]

1. We would like to measure Euclidean distances for crosshair positions in the MRI viewer. Is it possible to export them to Matlab?
2. One additional request regarding the MRI viewer: In clinical MRI viewers, the display is smoothed. This function is already available in Brainstorm for time-frequency plots. Could you establish that for the MRI viewer as well?

@mheers, thank you for your suggestions.

We would like to measure Euclidean distances for crosshair positions in the MRI viewer. Is it possible to export them to Matlab?

A way to get the current cross position with the MRI Viewer figure open:

sMri = panel_surface('GetSurfaceMri', gcf);
Handles = bst_figures('GetFigureHandles', gcf);
coords =  figure_mri('GetLocation', CoordinateSystem, sMri, Handles); % in meters

The CoodinateSystem can be 'voxel', 'mri', 'scs', 'mni', 'world'.
See this links for more details on each coord system:

We will take a look to this. @tmedani

Thanks a lot for the explanation on how to export the cursor position from the MRI viewer. It we probably safe us a lot of time!

Best regards,
