Problem with force plate data streaming

[mohsen]

We have 6 Kistler force plates. The data collection inside Motive works. Now I want to stream data and I am using the MATLAB code NatNetPollingSample (using the loopback interface).

The code does stream rigid body data. But for force plate data I have encountered 2 problems:
1- The number of forceplate (channels?) reported by data.nForcePlates varies from 0 to 18 from packet to packet.

2- Even when there does seem to be data streaming, I am not sure how to access the data. Using For example, data.ForcePlates(1).ChannelData returns the result below but I'm not sure how to get the measurement values.

Code: Select all

>> data.ForcePlates(1).ChannelData

ans = 

AnalogChannelData[] with properties:

Length:    32
LongLength:    32
Rank:    1
SyncRoot:    [1x1 NatNetML.AnalogChannelData[]]
IsReadOnly: 0
IsFixedSize: 1
IsSynchronized: 0
