Class FslEV3

IO helper to read FSL's EV3 files.

This is a three-column textfile format that is used to specify stimulation protocols for fMRI data analysis in FSL's FEAT module.

Data is always read as float.

Instance Methods

new empty dictionary

__init__(self, source)
Read and write FSL EV3 files.

source code

getNEVs(self)
Returns the number of EVs in the file.

source code

getEV(self, evid)
Returns a tuple of (onset time, simulus duration, intensity) for a certain EV.

source code

tofile(self, filename)
Write data to a FSL EV3 file.
