 +**Customer Request:**
  
-**customer request:**+I am using the temporal distance (with metric pipeline commands) script from your website, however, I'd like to calculate the parameters by stride instead of using the Global StrideVectors_MEAN. First, I calculated vector between events to create a Right StrideVectors and Left StrideVectors. To compute stride width, do I cross the LeftStep vectors with the Left StrideVectors or Right StrideVectors.

-you would cross the left with the right if you want the starting event to match. +You would cross the left with the right if you want the starting event to match. 
-one problem you are going to run into is that there won't always be a matching stride vector for each step vector. to fix this, you might want to create new hs and to events for each side calculation so that you will always have the correct number of events to calculate the metrics. +One problem you are going to run into is that there won't always be a matching stride vector for each step vector. To fix this, you might want to create new HS and TO events for each side calculation so that you will always have the correct number of events to calculate the metrics.
