Modify the Translators information

If you use a SACR marker instead of the LPSI and RPSI markers and need to run the CGM2 - Functional Calibration pipeline operation, to enable CGM2 to work with Nexus, you need to modify the information about the relevant markers. This information is stored in the Translators section of the CGM1-pyCGM2.settings file and the CGM1.translators file. To modify the information:

1. Copy the pyCGM2 folder from:
   C:\Program Files (x86)\Vicon\Nexus2.#\Python\Lib\site-packages\
   to
   C:\ProgramData
   
   
2. Depending on how often you use a SACR marker, edit the Translators information:
   
   
   • If you use the SACR marker by default:
     1. Edit this file:
        C:\ProgramData\pyCGM2\CGM1-pyCGM2.settings
     2. Under Translators , change:
        LPSI: None and RPSI: None to
        LPSI: SACR and RPSI: SACR
        
        
   • If you use the SACR marker in only some sessions:
     1. Copy this file into the relevant session folder:
        C:\ProgramData\pyCGM2\translators\CGM1.translators
     2. Edit the file as described above.
