+====== Compute Volume Of Chest Wall ======
-===== marker placement =====
+This command is based on the article by Ferrigno et al (1994) J Appl Physiol 77(3) 1224-1231.
-the command expects all 32 vertices described in the article.
+==== Marker Placement ====
-if any markers/landmarks are missing in a frame, no volume is computed.
