Target

  1. Create visualization of experimental tests in modeling (image) coordinate system.
  2. Prepare experimental data for model inputs.

Registration

  1. Download joint mechanics .zip file from Downloads page.
  2. Download the desired registration markers and bone STLs (place in folder named mri-oks00x, where x is the specimen ID).
    • 3 registration marker stls for tibia
    • 3 registration marker stls for femur
    • stl for tibia bone
    • stl for femur bone
  3. Create registration xml (Example Registration XML)

  4. Run script from command line Registration Script

    1. Change directory to desired OpenKnee specimen (e.g. oks001)

    2. Run convert_to_image_CS.py <oks00x_registration_0x.xml> <1>

Example using oks001 - 004_passive flexion
White stls - segmentation from MRI. Colored registration marker stls - spheres from calculated center of digitized points.

Re-sample Data for Model Input

  1. Create text file with desired tdms file(s) you would like to re-sample. Place this text file in either the KinematicsKinetics directory of the PatellofemoralJoint or TibiofemoralJoint mechanics directories depending on which data you are interested in re-sampling. Example text file for PatellofemoralJoint

  2. Place in the appropriate directory KinematicsKinetics of either the TibioFemoral or PatelloFemoral test directories.

  3. Run script from command line Re-sampling Script

    1. Change directory to desired OpenKnee specimen (e.g. oks001)

    2. Run resampling_potting.py <oks00x_registration_0x.xml> <oks0x_xF.txt>

See Sample Passive Flexion Video for video example.
