nmrglue.convert

Functions to convert between NMR file formats

This modules is imported as nmrglue.convert and can be called as such.

High-Level Classes

These are the classes most users will use from the convert module.

class nmrglue.fileio.convert.converter

The converter object allowes conversion between NMR file formats

Example:

vdic,vdata = ng.varian.read("varian_dir")
C = ng.convert.converter()
C.from_varian(vdic,vdata)
pdic,pdata = C.to_pipe()
ng.pipe.write("test.fid",pdic,pdata)

from_bruker(dic, data, udic=None)

Load data and dictionary from Bruker ser/fid file

from_pipe(dic, data, udic=None)

Load data and dictionary from NMRPipe pair

from_sparky(dic, data, udic=None)

Load data and dictionary from Sparky pair

from_universal(dic, data)

load data from universal dic,data pair

from_varian(dic, data, udic=None)

load data and dictionary from varian fid pair

Parameter:

• dic Varian dictionary
• data Varian data
• udic Universal dictionary. If not provided is guessed.

to_bruker()

Return Bruker dic,data pair

to_pipe(datetimeobj=datetime.datetime(2011, 4, 6, 16, 39, 24, 715461))

Return NMRPipe dic,data pair

to_sparky(datetimeobj=datetime.datetime(2011, 4, 6, 16, 39, 24, 715465), user='user')

Return sparky dic,data pair

to_universal()

Return universal dictionary and original data

to_varian()

Return Varian dic,data pair

Low-Level Classes

These classes are typically not used directly by users. They are used by high level functions. Developers and user who want fine control over file conversion will be interested in these functions.

class nmrglue.fileio.convert.udata_nd(edata, iproc, oproc, odtype, order=None)

Wrap other fileiobase.data_nd derived objects with input/output conversion when slices are requested.

• 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.
