Software @ CIS : lddmm-volume : Validationabout | tutorial | validation | manual | BIRN Portal | namespace | faq | credits | changelog | feedbackContent OverviewThe LDDMM Validation section provides input data, processing and visualization examples for LDDMM to ensure correctness of the resultant data. These examples are useful tests when LDDMM is run on new environments or platforms. Example images show atlas volume in red. On the left, the original target is in grey. On the right, the deformed atlas is pictured. A sample LDDMM command is posted with each example (click here or type ${LDDMM_HOME}/lddmm --help for more LDDMM usage information).Environment VariablesThe LDDMM application requires that two variables be set. Within CIS, there are two configurations.Linux DesktopLDDMM_TMP=/tmpRock Cluster Sphere TestDeforming Sphere Input (64x64x64) in tar+gzip format : A sphere expanding outward evenly in all directions.Output in tar+gzip format (100 MB) ${LDDMM_HOME}/lddmm -A Ball3D_1.img -T Ball3D_2.img
