usage: 'NAME',mode,value,param,flag T

The surface objects commands ('T') allow you to select and manipulate 3D objects (e.g. fiber tracks).

The MODE argument controls what type of object command to perform.
MODE:

• 0 - turn off PARAM bit(s) for objects in ROI
  • NAME - ROI mask image (default is previous window)
  • VALUE - index of ROI region (see FLAG)
  • PARAM - bit value in object parameter (default=1)
  • FLAG:
    • 0 - set all objects
    • 1 - VALUE is ROI num if ROIs, else intensity (default)
    • 2 - VALUE is intensity value
• 1 - turn on PARAM bit(s) for objects in ROI
  • NAME, VALUE, PARAM, and FLAG same as mode 0.
• 2 - turn off PARAM for active objects not passing through ROI
  • NAME, VALUE, PARAM, and FLAG same as mode 0.
• 3 - in/activate objects based on parameter value (ObjectParam) stored with each
  • PARAM - mask flag
    • 0 - in/activate where (ObjectParam & VALUE) is non-zero.
    • >0 - in/activate where (ObjectParam & VALUE) == PARAM.
  • FLAG - If 0 inactivate, else activate
• 4 - in/activate objects based on number of data points
  • PARAM - Control flag
    • 0 - objects with at least VALUE points
    • 1 - objects with less than VALUE points
    • FLAG - If 0 inactivate, else activate
• 5 - set/clear param for objects where ??
  • NAME - object param subset name
• 7 - save active objects as new data set
  • NAME - new data set name
• 8 - set OBJFLAG to VALUE
  • If VALUE is omitted this displays current OBJFLAG value
• 9 - set OBJMASK to VALUE
  • If VALUE is omitted this displays current OBJMASK value

Note: object parameter bit 1 means object is active

Examples:

Turn off all objects:
  0,0,1,0T
Turn on only objects with at least 50 points:
  4,50,0T
Turn off objects with less than 100 points:
  4,100,1,0T
