The acquisition profile
A new protocol doesn’t contain an acquisition profile. The best way to create an acquisition profile is to connect Odin to the hardware (Coda-hub or mini-hub). Odin will automatically select the different parameters of the acquisition profile in line with the hardware setup. To do so, simply click on “Hardware / select hardware server”, choose the server to connect and then the hardware configuration you need to use for your experiment. In the event that you cannot connect Odin to the hardware, you can create / add a new profile by right clicking on “Acquisition Profiles” and select “Add New …”
A new menu will appear.
You may create an acquisition profile by selecting a combination of hardware that you will use during your experiment.
Here are three different examples of hardware combination:
- CX1 + GS Analog Board. Choose this configuration if you want to collect data of marker position (CX1) and analogue channels / force plate data (analogue plate) using an old active hub (hub with mouse, keyboard and screen).
- CX1 + National instruments Analog Board. Choose this configuration if you want to collect data of marker position (CX1) and analogue channels / force plate data (analogue plate) using the new generation of Coda-Hub (hub with little touch screen integrated)
- CX1. Choose this configuration if you want to collect marker data only (mini or Coda-hub).
In our example, we will only choose “CX1”. To do it, tick the “CX1” option and click on “OK”. A new window will appear.
This window is used to set the names of the markers, the sampling rate, the acquisition time, start delay. Note that the red cross on the CX1 tab indicates that Odin is not connected to the system. For our quick protocol, first indicate a name for your protocol. Secondly rename the markers 1 to 4 with the following name: “RThigh.0”, “RThigh.1”, “RThigh.2”, and “RThigh.3” and markers 5 to 8 by “R.Shank.0”, “R.Shank.1”, “R.Shank.2”, and “R.Shank.3” (Note that you can use the define cluster option to rename marker having the same prefix in a quicker way). Then untick marker 9 to 56. Choose the sampling rate of 100Hz and set the recording time to 10 seconds. Then click on “OK” to validate the changes.
A new item will appear on the “Acquisition Profile” section as show below.
The acquisition profile can be modified at any moment by right clicking on it and selecting “Edit …”.
