* <span style="color:blue">'''''Image Files and Parameters''''' </span> 
** <span style="color:green">'''Input Image Volume'''</span> [<span style="color:orange">--inputVolume</span>] : Required: input image file name containing multiple baseline gradients to average
** <span style="color:green">'''Output Image Volume'''</span> [<span style="color:orange">--outputVolume</span>] : Required: name of output NRRD file containing directly averaged baseline images
** <span style="color:green">'''Directions Tolerance'''</span> [<span style="color:orange">--directionsTolerance</span>] : Tolerance for matching identical gradient direction pairs ''Default value: 0.01''
** <span style="color:green">'''Average B0 Only'''</span> [<span style="color:orange">--averageB0only</span>] : Average only baseline gradients. All other gradient directions are not averaged, but retained in the outputVolume ''Default value: 0''
