time of two events should be the same. about openma HOT 7 CLOSED

There is no C3D file attached with your issue :-)

from openma.

sorry.
here it is.
gait Trial 01 - Copy.txt
Notice, i change extension to upload it in github.

from openma.

There is a difference of 0.001 second (2.52 vs 2.521). Can you explain how you compute the time for each event? Maybe your computation for the frame associated with the left foot strike is not an integer value but a real and the result is something like 253.00001. In this case, you need to take only the integer part of the result (with a method like floor).

i generate this event in Nexus manually
it dont come up through any calculation.

So why the problem comes from OpenMA? In the C3D EVENT:TIMES parameters, the times are set to 2.52 and 2.521. The problem might come from the program that generates the event then.

General events were generated with Nexus

The time stored in the C3D file for your Left Foot Strike is 2.521. This means the method used to generate it found that the frame is 252.1. This might be possible if the force plate was used for this event (the sample frequency is 100Hz). In any case, this is not related to OpenMA.
