Remove Component(s)


Artifact signals like eye blinks, eye movements, muscle activity, etc make the detection of brain activity difficult. Therefore, signal processing techniques should be used to remove the artifacts from the data. ICA can be used to remove the components from the fMRI data. This can be done in GIFT by selecting 'Remove Component(s)' entry from the Utilities drop down box. After the calculation is done, new set of images with prefix 'R_' are written in the selected output directory.  These new set of images can be analyzed using ICA or SPM.
