(mode='IUPAC')[source]¶ on a 2D experiment, assuming the F2 axis is 1H try to detect spin nature from frequency, and apply the unified scale as proposed by IUPAC-2001
Harris et al. NMR Nomenclature: Nuclear Spin Properties and Conventions for Chemical Shifts—IUPAC Recommendations. Journal of Magnetic Resonance (2002) vol. 156 (2) pp. 323-326
- WARNING, a different setting for biomolecules was proposed in a IUPAC/IUB recommendation in 1998
Markley et al. Recommendations for the presentation of NMR structures of proteins and nucleic acids. Journal of Molecular Biology (1998) vol. 280 (5) pp. 933-952
This previous recommendation was only mentionning 2D 13C, 15N and 31P, but was using different references
Usage is to use 1998 recommendation for proteins and nucleic acids. these are enforced when mode = “IUB” or “biomolecule” this makes +2.6645 ppm shift in 13C. this makes a +380.4434 ppm shift in 15N.
Returns the name of the defined nucleus in F1, “15N” “13C” “31P” or “None” if nothing was done

IDEM, for 15N proteins tend to use NH3 reference, where IUPAC imposes MeNO3 this makes a +385.50 ppm shift in 15N.

bucket
(start=0.5, end=9.5, bsize=0.04, file='bucket.cvs')[source]¶ This tool permits to realize a bucket integration from the current 1D data-set. You will have to determine (all spectral values are in ppm)
start, end : the starting and ending points of the integration zone in the spectrum
bsize : the size of the bucket
file :the filename to which the result is written
the “set to current window” button defines the starting and ending points of the integration zone from the current zoom window the “record” button permits to memorize the current parameters, which will be reused for the bucket integration. the “details” button displays the number and the size of the buckets currently defined. a non-integer size means that the integration will be performed on a varying number of data points
in order to insure a constant integration width in ppm. However, the integration intensity is not modified by the integration width.
- For a better bucket integration, you should be careful that :
the bucket size is not too small, size is better than number !
the baseline correction has been carefully done
the spectral window is correctly determined to encompass the meaningfull spectral zone.

minimal error checking, done mostly by the FT operations.
Note that a small apodisation is done on the Fourier transform to reduce truncation artifacts you might want to remove this in certain cases, for instance if you plan to have several hilbert() applied to the same data in sequence.

despite the name, not quite the inverse of hilbert() !

proc3d
(sourcefile, destinationfile, plane_to_process, commands, context)[source]¶ this macro processes a 3D file using the cache system (join, getc, putc) it permits to handle very large files, which would not fit into memory.
sourcefile : is the initial data-set destinationfile : is the result of the process plane_to_process : either F1, F2 or F3 (NOT F12 or F123)
F1 means : planes perpendicular to F1, thus the planes containing the F2 and F3 axes.
commands : a string holding the commands to be applied to each plane in 2D notation context : a dictionary containing the variables needed to execute commands,
i.e. exec(commands,context) will actually be used usually built from globals() and locals()
the commands are the regular commands you would used to process a 2D data-set. when called without parameters, ‘commands’ can be several line long, as typed when proc3d is called with parameters on the line, then ‘commands’ should be a single command line within quotes.
e.g. proc3(ser_file, F1_proc, “F1”, ‘sin(0.2,”f12”); ft_sim(); phase(30,-40,f2); real(“f12”); ft_tppi()’)
# process axes f3 and f2 as 2D
- proc3(F1_proc, full_proc, “F2”, ‘sin(0.2,”f1”); ft_tppi(); real(“f1”); bcorr(3,”f1”)’)
# process axis f1
would process a whole 3D in 2 steps.

Markley et al. Recommendations for the presentation of NMR structures of proteins and nucleic acids. Journal of Molecular Biology (1998) vol. 280 (5) pp. 933-952 This previous recommendation was only mentionning 2D 13C, 15N and 31P, but was using different references They are given in table 4 of 2001 paper

- when extracted from the dictionnnary, values are interpreted in several manner
o 1K is replaced by 1024 and all multiples (4k; 24k; etc…) o 1M is replaced by 1024*1024 and all multiples (4M; 24M; etc…) o all arithmetic is evaluated : math.pi/2, 0.1*get_si1_2d(), etc…

spike.v1.Process1D module¶
This module contains all the routines needed to process 1D NMR spectra
The following functions realize a set of operations, needed for NMR 1D processing, You will find operation for FT analysis, MaxEnt Analysis, Inverse Fourier, etc..
Processing are divided in pre - FT - Post phases. For instance a typical 1D procesing, would be
pre() ft() post()
but other combinations are possible.
Most functions take the following arguments : arguments : audit
the opened audit file, if empty or set to none, audit will go to the stdout
- filein the file name of the input file,
will loaded before operation, if name is “memory”, then processing takes place on the current 2D kernel buffer
- fileout the file name of the input file, can be “memory”
will written after operation, if name is “memory”, then processing results is left in 2D kernel buffer
- p_in the dictionary containing all the processing parameters
most entries are optionnal as entries are protected with try / except
f_in the dictionary containing all the details on the spectrum “filein” f_out details on the spectrum “fileout” will be put in this dictionary location the directory where the output files will be written
