First Level within subject fMRI processing (1)

• Download

Overview - fMRI-FEAT workflow This is a simple with-in subject fMRI analysis workflow. It takes 3D fMRI images and structural images of a subject and performs FSLmerge, BET (if the data is not already skull stripped) and first level FEAT processing.   Problem addressed by this workflow FSLMerge, BET and FEAT first level analysis can be performed using this workflow on one or more subjects that require the same processing. The design FSF file is generate using the FSL FEAT inte...

Local Shape Analysis (LSA) Workflow (1)

• Download

This workflow takes raw un-skull-stripped volumes in 2 groups/populations and an ROI index to generate a color-coded shape object using the per-vertex local p-values of some local shape-measure (e.g., displacement, atrophy, Jacobian, curvature, etc). It also outputs the p-values color-map superimposed on the mean shape. Problem addressed by this workflow   Identifying local group differences between 2 populations in one specific ROI. This workflow also generates mean-shape DX mo...

Global Shape Analysis Workflow (1)

• Download

This workflow takes raw un-skull-stripped volumes in multiple groups/populations, or a Study-Design, and generates a scene file containing the models of the ROIs where the groups are different. It also reports the global 56 regional p-values. Problem addressed by this workflow   Identifying the group differences between 2 populations in the global shapes of 56 cortical and sub-cortical ROIs. This workflow also generates DX models of all 56 ROIs which can be viewed as a scene in Sh...
