Workflow First Level within subject fMRI processing (1)

Thumb
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...

Workflow Image Registration Meta Algorithm (IRMA) (1)

Thumb
Overview - Workflow-Title In this workflow different registration algorithms are applied to the same image and the image that is best registered to the template is chosen as the output top candidate.   Problem addressed by this workflow In this workflow various registration algorithm is performed on the same subject. The algorithm that gives the best result is chosen. This might be different for different input images. This workflow is robust and picks the best-registered imag...

Workflow Direct Hippocampal Mapping (1)

Thumb
Overview - Direct Hippo Mapping The workflow takes volumetric masks of hippocampi from two groups, generates surfaces from each mask, and maps these surfaces to a hippocampal atlas. It also computes thickness and displacement feature on the surfaces and evaluates the statistical significance of the differences between the two groups with respect to these measurements.   Problem addressed by this workflow Automatically establishing correspondences between points on hippocampal ...

Workflow Minimum Deformation Template (MDT) Atlasin... (1)

Thumb
This pipeline present the redesigned automated workflow for constructing the Minimum Distance Template (MDT) atlas for a given population, based on one specific image modality (e.g., sMRI). There will be two specific validation examples based on 100+ ICBM subjects: Quantitative: The ICBM data will be registered to the MDT, NRU and ICBM 462 atlases and mean displacement stats across all subjects will be reported for each voxel. The distributions of these mean displacement magnitud...

Workflow Automated Cortical Surface Extraction Work... (1)

Thumb
This workflow takes raw un-skull-stripped volumes and generates a cortical surface model using FreeSurfer? and CCB tools. Problem addressed by this workflow There are many ways to generate cortical surface models based on MRI data. Here is one of them. Eventually, there will be a new Learning-based Cortical Surface Modeling Pipeline, as well.   Input is Raw MRI T1-weighted volume CCB/FreeSurfer Cortical Surface extractor that the SIG-Shape team developed and we validated ...

Workflow Local Shape Analysis (LSA) Workflow (1)

Thumb
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...
