Hi Lincoln,

Obtaining the volume of a mask layer in Seg3D is as simple as clicking on the information icon in the layer (looks like an 'i') and clicking calculate to calculate the volume.  However, it sounds like you need help segmenting out the region you want to measure.  It is difficult to understand what help you need from your description.  Manual methods (paint brush, polyline) are the most accurate on average, though they are time consuming and may be less precise.  A lot of data requires some combination of automatic and manual tools in order to get really accurate and precise segmentations.  Try the threshold tool and then use the paint brush to clean it up.  If you would like more specific help, you can send a screen shot or something to give a better idea of the data that you need.

"Dear author's Seg3d 2.1 tutorial PDF,

I am Ph.D. student and I am trying to measure the volume of the root canal filling material in the isthmus of mandibular molars mesial canals (the material in the space between the canals). How can I measure just the volume in the isthmus excluding the filling material inside the main canals lumen?
In the data filters I selected the neighborhood connected and put seed points in the filling material. I can measure the total volume of the canal filling, including the two canals of the mandibular mesial root and isthmus area, but I don´t know how to measure only the isthmus.
I could select the paint tool or polyline tool this area, but it is difficult and not very trustful… There is an easier way to do that?
If you could help me, I would be very glad.
Thank you"

If you could help me with it I would be very glad.
