  1. Usage of REST-GCA ZANG Zhenxiang zangzx416@gmail.com

  2. Outline • Set data directory • Set ROI • Mask selection • Set order & select algorithm • Set covariates (optional) • Set output directory • Z score transformation

  3. Set directory • Click the right button to add a directory: ← →

  4. Set directory • Add sub-folders for batch analysis: ← →

  5. Set directory • Remove the selected directory: ← →

  6. Set directory • Remove all the directories: ← →

  7. Set ROI • Voxel-wise • ROI-wise

  8. Voxel-wise →

  9. Voxel-wise → Please see REST-sliceviewer for details. → The text file must contain only one column. Each line represents the value of a time point. →

  10. Set ROI • Voxel-wise • ROI-wise

  11. ROI-wise (between two ROIs) Set the first ROI: →

  12. ROI-wise → Please see REST-sliceviewer for details. → The text file must contain only one column. Each line represents the value of a time point. →

  13. ROI-wise Three ROIs have been added

  14. Mask selection → → →

  15. User defined mask • Select your mask: ←

  16. Order and algorithm • Set order: • Choose the algorithm: or

  17. Select the Coefficient Mode Bivariate coefficients is for bivariate cGCA computation. Multivariate coefficients is for multivariate cGCA computation. The two selection are based on coefficient-based ROI-wise GCA. →

  18. ROI-wise for bivariate c-GCA outputs → ROI_sequence: save the sequence of pair ROI for bivariate GCA. Three pairs of computation have been performed: ROI1 v.s. ROI2; ROI1 v.s. ROI3 and ROI2 v.s. ROI3. Bivariate Results: Order was 1. Left column is the signed-path coefficients (ROI1 v.s. ROI 2,… see ROI_sequence). Right column is the auto regression coefficients.

  19. ROI-wise for Multivariate c-GCA Order1 results: Order2 results:

  20. Add covariates • Covariates are optional ↓ → The covariates text file may contain several columns, each respresenting a covariate.

  21. Set output directory → ←

  22. Z score transformation The result maps will be renamed with suffix letter ‘Z’

  23. Click ‘Compute’ to start

  24. Thanks for using REST and REST-GCA!
