GCOR brick¶
Using AFNI GCOR, computes the average correlation between every voxel and every other voxel, over any given mask¶
Mandatory inputs parameters:
- in_file (a string representing an existing file)
Input image.
ex. '/home/username/data/derived_data/mean_reg_func_valid.nii'
Optional inputs with default value parameters:
- combine (a boolean, optional, default value is True)
Combine the final measurements along each axis.
ex. True
- no_demean (a boolean or an integer, optional, default value is False)
Do not (need to) demean as first step.
ex. False
Optional inputs:
- mask_file (a string representing an existing file, optional)
Mask image.
ex. '/home/username/data/derived_data/automask_mean_reg_func_valid.nii'
- nfirst (an integer, optional)
Number of initial TRs to ignore. Default is Undefined (ie parameter not used)
ex. 3
Outputs parameters:
- out (a float)
Global correlation.
ex. 0.06123
