Frequencies of GRF and Marker coodinates

Post by Kang Li » Sun Nov 15, 2009 1:56 pm

Hi All,

I am wondering if frequencies of GRF and Marker coodinates need to be converted to the same so that the number of the data rows in motion data file is the same as that in GRF file

Kang,

Nope. The number of rows does not matter. The "time" value however should correspond.

In short the frequency should match but the sampling does not have to.
