Two levels' ICA can disclose steady-state and transient profiles

The code below is dependent on GIFT, FSL and AFNI. It shows the 2nd level ICA since the 1st level can be done through GIFT, FSL melodic etc..

Transient information can be retrieved by using the saved subject's profile as weight (per the analysis of the paper) to be multiplied to the dynamic profiles given by GIG-ICA or any other back-reconstruction method (such as dual regression).
