brukerapi 0.2.2

Bruker API

brukerapi-python

A Python package providing I/O interface for Bruker data sets.

tl;dr

Install using pip:

pip install brukerapi

Load any data set:

from brukerapi.dataset import Dataset
dataset = Dataset('{path}/2dseq')    # create data set, works for fid, 2dseq, rawdata.x, ser
dataset.data                         # access data array
dataset.VisuCoreSize                 # get a value of a single parameter

Load an entire study:

from brukerapi.folders import Study
study = Study('{path_to_study_folder}')
dataset = study.get_dataset(exp_id='1', proc_id='1')

# get_dataset returns an empty dataset
# in order to load data into the data set, you can either use the context manager:

with dataset as d:
    d.data                         # access data array
    d.VisuCoreSize                 # get a value of a parameter

# or the load function
dataset.load()
dataset.data                       # access data array
dataset.VisuCoreSize               # get a value of a single parameter

Load a parametric file:

from brukerapi.jcampdx import JCAMPDX

parameters = JCAMPDX('path_to_scan/method')

TR = data.params["PVM_RepetitionTime"].value # This way
TR = data.get_value("PVM_RepetitionTime") # Or this way

Features

• I/O interface for fid data sets

• I/O interface for 2dseq data sets

• I/O interface for ser data sets

• I/O interface for rawdata data sets

• Random access for fid and 2dseq data sets

• Split operation implemented over 2dseq data sets

• Filter operation implemented over Bruker folders (allowing you to work with a subset of your study only)

Examples

• How to read a Bruker fid, 2dseq, rawdata, or ser file

• How to split slice packages of a 2dseq data set

• How to split FG_ECHO of a 2dseq data set

• How to split FG_ISA of a 2dseq data set

Documentation

Online documentation of the API is available at Read The Docs.
