This command downsamples all TARGET signals or all ANALOG signals in a C3D file by an integer multiple. Note: This is a hidden and unsupported command

If you are modifying the ANALOG rate then it will be necessary to ensure that the resulting ANALOG rate is an integer multiple of the TARGET rate.

Given a C3D file with a POINT rate of 50 Hz and an ANALOG rate of 200 Hz , downsample the POINT signals to 25 Hz.

Given a C3D file with a POINT rate of 50 Hz and an ANALOG rate of 200 Hz, downsample the ANALOG signals to 100 Hz.

The pipeline command Upsample_Point_Data_to_Analog_Rate upsamples the point data of a C3D file to match the analog rate using a cubic spline.
