class mvpa2.misc.bv.base.BrainVoyagerRTC(source)

IO helper to read BrainVoyager RTC files.

This is a textfile format that is used to specify stimulation protocols for data analysis in BrainVoyager. It looks like

FileVersion: 2 Type: DesignMatrix NrOfPredictors: 4 NrOfDataPoints: 147

“fm_l_60dB” “fm_r_60dB” “fm_l_80dB” “fm_r_80dB” 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000

Data is always read as float and header is actually ignored

Attributes

ncolumns	Returns the number of columns.
nrows	Returns the number of rows.

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, ...)
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), ...)
toarray()	Returns the data as an array
tofile(filename[, header, header_order, sep])	Write column data to a text 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(...)
