Re: [caret-users] Generate 3D coordinates list?
You may need to use File: Convert Data File Formats (or command line tool caret_file_convert) to convert the coord file to ASCII.

Re: [caret-users] Generate 3D coordinates list?
Do you want a list of all coordinates? Or do you want to know the center of gravity of the nodes within a region. To compute the later, simply use the region of interest tool to select those nodes and then in OPERATION, change the option to statistical report on selected nodes. The output will list the center of gravity for those nodes. Hope that helps. Best Regards, Donald McLaren = D.G.

Try this, * Select the nodes in your ROI. * Change "Normal Selection" to "Not Selection" and then press the "Select Nodes" button. You should now see all of the nodes in the ROI deselected and all nodes NOT in the ROI selected. * Set the Operation Surface and Topology Surface to the surface in the main window. * In the Operate on Selected Nodes section, set the Operation to Disconnect Selected Nodes and press the Disconnect Selected Nodes button. All nodes except those in your original ROI will disappear. * Save the coordinate and topology files for the surface remaining in the main window as ASCII (text) files. * If you view the contents of the coordinate file, all disconnected nodes are moved to the origin and thus have a coordinate of (0.0, 0.0, 0.0).
