cortex.utils.get_dropout

cortex.utils.get_dropout(subject: str, xfmname: str, power: float = 20)

Create a dropout Volume showing where EPI signal is very low.

Parameters:

subjectstr

Name of subject

xfmnamestr

Name of transform

powerfloat, optional

Exponent applied to the normalized (inverted) signal intensity; larger values make the dropout mask more conservative (only the lowest-signal voxels are marked as dropout). Default 20.

Returns:

volumedataview

Pycortex volume of low signal locations
