mvpa2.misc.fsl.base.FslEV3

Inheritance diagram of FslEV3
class mvpa2.misc.fsl.base.FslEV3(source)

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.

Attributes

durations
intensities
ncolumns Returns the number of columns.
nevs Returns the number of EVs in the file.
nrows Returns the number of rows.
onsets

Methods

clear()
copy()
fromkeys(S[,v]) v defaults to None.
get(k[,d])
get_ev(evid) Returns a tuple of (onset time, simulus duration, intensity) for a certain EV.
has_key(k)
items()
iteritems()
iterkeys()
itervalues()
keys()
pop(k[,d]) If key is not found, d is returned if given, otherwise KeyError is raised
popitem() 2-tuple; but raise KeyError if D is empty.
select_samples(selection) Return new ColumnData with selected samples
setdefault(k[,d])
to_events(**kwargs) Convert into a list of Event instances.
tofile(filename) Write data to a FSL EV3 file.
update([E, ]**F) If E present and has a .keys() method, does: for k in E: D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]
