SelectActivations

SelectActivations[act]

selects the activations above the given ActivationSize.

SelectActivations[act,vox]

selects the activations above the given ActivationSize where the activation size is in mm^3.

SelectActivations[act,mask]

selects the activations above the given ActivationSize within the given mask or masks. The mask can be 3D or 4D.

SelectActivations[act,{mask,back}]

selects the activations above the given ActivationSize within the given mask or masks. All voxels outside the back are ignored. Output is {actSelected, actTotal} is mask is 3D. Output is {{actSelected, Total[actSelected]},{actTotal,Total[actTotal]}} is mask is 4D where actSelected and actTotal are per mask.

Details

  • The following options can be given:
  • ActivationSize4ActivationSize is an option for SelectActivations. Its the size of the activations selected defined in number of voxels if no voxel size is given. If a voxel size is given its the volume.
    IgnoreSlices{0, 0}IgnoreSlices is an option for FindActivations and SelectActivations. Determins how many slices of the start and end of the dataset are ignored.
