nmrglue.fileio.varian.read_lowmem

nmrglue.fileio.varian.read_lowmem(dir='.', fid_file='fid', procpar_file='procpar', read_blockhead=False, shape=None, torder=None)[source]

Read Agilent/Varian files in a directory using minimal amount of memory.

Parameters

dirstr, optional: Directory holding Agilent/Varian data. Default is the current working directory.
fid_filestr, optional: Filename of binary (fid) file in directory.
procpar_filestr, optional: Filename of procpar file in directory.
read_blockheadbool, optional: True to read blockheader(s) and return then in the Agilent/Varian parameter dictionary. False (default) does not perform this reading.
shapetuple of ints, optional: Shape of data in binary file. None (default) will attempt to finds this automatically.
torder{None, ‘r’, ‘o’, ‘f’ or a Python function} , optional: Description of the mapping of traces in the file to the NMR data matrix. None (the default) will attempt to find this automatically which is typically fine for most NMR experiments. See read() for additional details.

Returns

dicdict: Dictionary of Agilent/Varian parameters.
dataarray_like: Low memory object which can access NMR data on demand.
