Sorting Components
Sorting is a way to classify the components. For every independent
component spatial maps and time courses are generated. Components can be sorted
in two ways:
- Temporal Sorting
- Spatial Sorting
Select 'Yes' for sort components in the Component Explorer and click Display button then a dialog box
will pop up that shows the information about the sorting. Click Ok for the
dialog button and then a figure will open in a new window. Figure below shows
the completed parameters.

The following are the definitions of the parameters:
- Sorting Criteria
- There are three different types of sorting criteria like Multiple
Regression, Correlation, Kurtosis and Maximum Voxel.
- What do you want to sort?
- There are four options for temporal sorting depending upon the number of
subjects and sessions you select.
- Select any Subject any session - A particular subject's session is
selected and correlated with the model time course.
- Select a particular session of all subjects - A particular session for
all subjects is selected, time courses are concatenated and correlated with
the concatenated model time course.
- Select a particular Subject - A particular subject's sessions are
selected, time courses are concatenated and correlated with the model time
course.
- Select all Subjects and Sessions - All data sets are concatenated and
correlated with the model time course.
- Sorting Type
- Temporal or Spatial.
- Reference Function
- You have a good measure to separate the task related components depending
on the model time course or spatial template.
