[data,rKW,lKW,rAW,lAW] = JOINTWIDTHPIG_DATA(data,markerDiam) computes knee and ankle joint widths for PiG data ARGUMENTS data ... Zoo structure markerDiam ... Diameter of marker in mm RETURNS data ... Zoo structure with joint widths appended rKW ... right knee width (mm) lKW ... left knee width (mm) rAW ... right ankle width (mm) lAW ... left ankle width (mm) NOTES - This method is only used when anthropometric information is missing from anthro branch
