AA Tasklist Module Description

Main

Data

  • aamod_structuralfromnifti: find structural input files from nifti.
  • aamod_epifromnifti: find EPI input files from nifti.
  • aamod_tsdiffana: calculate measurements of noise in time series.
  • aamod_realign: uses SPM realignment to perform motion correction on fMRI data, realigning each image to the first one.

Structural

  • aamod_coreg_noss: spatially align (coregister) the mean fMRI volume with the structural.
  • aamod_norm_noss: noramlization. Scale and warp the structural image so that each brain region matches the corresponding one in the MNI standard template (average brain).

Functional

  • aamod_bet: use the FSL brain extraction tool (BET).
  • aamod_bet_epi_reslicing: skull stripping with BET.
  • aamod_mask_fromstruct: create different threshold masks from the segmentation.
  • aamod_compSignal: get the signal from the CSF, WM, GM, and OOB.
  • aamod_norm_write: apply the scaling and warping derived by norm_noss to the fMRI images.
  • aamod_smooth: spatially smooths the fMRI data.

Modelling

  • aamod_listspikes: lists spikes (big changes from one image to the next) in the MRI data.
  • aamod_firstlevel_scrubbingmodel_BS: cleans and filters time series.
  • aamod_firstlevel_modelestimate_saveresids: estimate a specified model and save the residuals.
