FindActivations
FindActivations[data]
Finds the activation in MUMRI or DTI data after data normalization.
FindActivations[data,mask]
Finds the activation in MUMRI or DTI data after data normalization within the mask.
Details
- The following options can be given:
-
ActivationThreshold {3., 0.75} ActivationThreshold is an option for FindActivations. Fist value is the number of standard deviations second is the percentage threshold. ThresholdMethod "Both" ThresholdMethod is an option for FindActivations. Values can be "StandardDeviation", "Fraction" or "Both". ActivationOutput "Activation" ActivationOutput is an option for ActivationOutput. If set to All also the mn and threshold values are returned. MaskDilation 0 MaskDilation is an option for Mask, SmoothMask and SmoothSegmentation. If the value is greater than 0 it will dilate the mask, if the value is smaller than 0 it will erode the mask. IgnoreSlices {0, 0} IgnoreSlices is an option for FindActivations and SelectActivations. determines how many slices of the start and end of the dataset are ignored. ActivationBackground 10 ActivationBackground is an option for FindActivations. If all normalized signals, which range between 0-150, are below this value the algorithm does nothing. ActivationIterations 10 ActivationIterations is an option for FindActivations. The maximum number of iteration that can be used for activation detection.
