mvpa2.misc.fsl.base.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.

Methods

clear(() -> None.  Remove all items from D.)
copy(() -> a shallow copy of D)
fromkeys(...)	v defaults to None.
get((k[,d]) -> D[k] if k in D, ...)
get_ev(evid)	Returns a tuple of (onset time, simulus duration, intensity) for a certain EV.
has_key((k) -> True if D has a key k, else False)
items(() -> list of D’s (key, value) pairs, ...)
iteritems(() -> an iterator over the (key, ...)
iterkeys(() -> an iterator over the keys of D)
itervalues(...)
keys(() -> list of D’s keys)
pop((k[,d]) -> v, ...)	If key is not found, d is returned if given, otherwise KeyError is raised
popitem(() -> (k, v), ...)	2-tuple; but raise KeyError if D is empty.
select_samples(selection)	Return new ColumnData with selected samples
setdefault((k[,d]) -> D.get(k,d), ...)
to_events(**kwargs)	Convert into a list of Event instances.
tofile(filename)	Write data to a FSL EV3 file.
update(([E, ...)	If E present and has a .keys() method, does: for k in E: D[k] = E[k]
values(() -> list of D’s values)
viewitems(...)
viewkeys(...)
viewvalues(...)

Read and write FSL EV3 files.

Parameters:

source : str

Filename of an EV3 file

durations

get_ev(evid)

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

intensities

nevs

Returns the number of EVs in the file.

onsets

to_events(**kwargs)

Convert into a list of Event instances.

Parameters:

kwargs :

Any keyword arugment provided would be replicated, through all the entries. Useful to specify label or even a chunk
