nmrglue.fileio.varian.fid_nd

class nmrglue.fileio.varian.fid_nd(filename, i2t_func, fshape=None, order=None)

Emulate a ndarray objects without loading data into memory for low memory reading of Agilent/Varian fid files which must have one trace per block.

• slicing operations return ndarray objects.

• can iterate over with expected results.

• transpose and swapaxes methods create a new objects with correct axes ordering.

• has ndim, shape, and dtype attributes.

Parameters

filenamestr

Filename of Agilent/Varian binary file.

i2t_funcfunction

Python function which maps an index to a trace.

fshapetuple of ints, optional

Shape of data in file, if None will be assumed to be 2D data.

ordertuple

Ordering of axes compared to file. None will results in (0, 1, 2, …) ordering.

__init__(filename, i2t_func, fshape=None, order=None)

Create and set up object.

Methods

__init__(filename, i2t_func[, fshape, order])	Create and set up object.
swapaxes(axis1, axis2)	Return object with axis1 and axis2 interchanged.
transpose(*axes)	Return object with axes transposed.
