stats_ttest_dependent(filea, fileb, target, output, exclude, verbose)

Computes t-test of differences between two dependent groups.

Parameters

--filea (str):

--fileb (str):

Either a single image or a conc file with data of the group to compare with.

--target (str):

The base filename (and path) to be used when saving the results.

--output (str, default 'medtpz'):

The type of results to save:

  • 'm' ... mean values for each voxel of both groups (A and B)

  • 'e' ... standard errors for each voxel of both groups (A and B)

  • 'd' ... the A - B difference of means of the two groups

  • 't' ... t-value for each voxel

  • 'p' ... p-value for each voxel

  • 'z' ... Z-score for each voxel.

--exclude (vector, default ''):

Values to be excluded from computation.

--verbose (bool, default false):

Should report each step.
