nmrglue.fileio.pipe.pipestream_4d

class nmrglue.fileio.pipe.pipestream_4d(filename, order=(0, 1, 2, 3))

Emulate a ndarray objects without loading data into memory for low memory reading of 4D NMRPipe data steams (one file 4D data sets).

• 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 4D NMRPipe stream file.

ordertuple

Ordering of axes against file.

__init__(filename, order=(0, 1, 2, 3))

Create and set up object

Methods

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