mne.transforms.Transform¶

class mne.transforms.Transform(fro, to, trans=None)[source]¶

A transform.

Parameters:	fro : str | int The starting coordinate frame. to : str | int The ending coordinate frame. trans : array-like, shape (4, 4) | None The transformation matrix. If None, an identity matrix will be used.

Attributes

from_str	The “from” frame as a string.
to_str	The “to” frame as a string.

Methods

__contains__((k) -> True if D has a key k, …)
__getitem__	x.__getitem__(y) <==> x[y]
__iter__() <==> iter(x)
__len__() <==> len(x)
clear(() -> None.  Remove all items from D.)
copy()	Make a copy of the transform.
fromkeys(…)	v defaults to None.
get((k[,d]) -> D[k] if k in D, …)
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.
save(fname)	Save the transform as -trans.fif file.
setdefault((k[,d]) -> D.get(k,d), …)
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(…)

__contains__(k) → True if D has a key k, else False¶

__getitem__()¶

x.__getitem__(y) <==> x[y]

__iter__() <==> iter(x)¶

__len__() <==> len(x)¶

clear() → None. Remove all items from D.¶

copy()[source]¶

Make a copy of the transform.

from_str¶

The “from” frame as a string.

fromkeys(S[, v]) → New dict with keys from S and values equal to v.¶

v defaults to None.

get(k[, d]) → D[k] if k in D, else d. d defaults to None.¶

has_key(k) → True if D has a key k, else False¶

items() → list of D’s (key, value) pairs, as 2-tuples¶

iteritems() → an iterator over the (key, value) items of D¶

iterkeys() → an iterator over the keys of D¶

itervalues() → an iterator over the values of D¶

keys() → list of D’s keys¶

pop(k[, d]) → v, remove specified key and return the corresponding value.¶

If key is not found, d is returned if given, otherwise KeyError is raised

popitem() → (k, v), remove and return some (key, value) pair as a¶

2-tuple; but raise KeyError if D is empty.

save(fname)[source]¶

Save the transform as -trans.fif file.

Parameters:	fname : str The name of the file, which should end in ‘-trans.fif’.

setdefault(k[, d]) → D.get(k,d), also set D[k]=d if k not in D¶

to_str¶

The “to” frame as a string.

update([E, ]**F) → None. Update D from dict/iterable E and 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]

values() → list of D’s values¶

viewitems() → a set-like object providing a view on D’s items¶

viewkeys() → a set-like object providing a view on D’s keys¶

viewvalues() → an object providing a view on D’s values¶
