library for handling NRG Systems data files

Project description

NRGPy nrgpy

nrgpy is the Python package for processing NRG Data Files

It provides tools for:

  • Converting binary ".rld" and ".rwd files to text format
    • using locally installed SymphoniePRO Desktop Software and Symphonie Data Retriever
    • using web api (compatible with Linux!) *(SymphoniePRO only at this time)
  • Reading Symphonie text exports into Pandas dataframes
  • Reading Spidar zip/csv files into Pandas dataframes
  • Timestamp adjustment (of text files)
  • Simple quality checks on data

Installation

pip install nrgpy

Examples

RLD files

Convert a folder of RLD files to Text with SymphoniePRO Desktop Software

from nrgpy.convert_rld import local
date_filter = '2018-10' # filter on any text in the filenames
text_folder_name = 'text_outputs/'
converter = local(rld_dir='', out_dir=text_folder_name, file_filter=date_filter)
converter.convert()

Convert a folder of RLD files to Text with NRG Convert API

from nrgpy.convert_rld import nrg_convert_api
file_filter = "000175"
rld_directory = "rlds"
client_id = "contact support@nrgsystems.com for access"
client_secret = "contact support@nrgsystems.com for access"
converter = nrg_convert_api(
    file_filter=file_filter, 
    rld_dir=rld_directory, 
    client_id=client_id,
    client_secret=client_secret,
    start_date="2019-11-01",
    end_date="2019-11-30",
)
converter.process()

Convert a single RLD file to Text with NRG Convert API

from nrgpy.convert_rld import nrg_convert_api
filename = "/home/user/data/sympro/000123/000123_2019-05-23_19.00_003672.rld
txt_dir = "/home/user/data/sympro/000123/txt/"
client_id = "contact support@nrgsystems.com for access"
client_secret = "contact support@nrgsystems.com for access"
converter = nrg_convert_api(
    file_filter=file_filter, 
    filename=filename, 
    client_id=client_id,
    client_secret=client_secret,
)

Read files

file_filter = "000175"
from nrgpy.sympro_txt import sympro_txt_read

sympro_dfs = sympro_txt_read()
sympro_dfs.concat_txt(
    txt_dir=text_folder_name, 
    file_filter=file_filter, 
    start_date="2019-11-01",
    end_date="2019-11-30",
)

Read with more options...

from nrgpy.sympro_txt import sympro_txt_read

sympro_dfs = sympro_txt_read()
sympro_dfs.concat_txt(
    txt_dir=text_folder_name, 
    file_filter="000175", 
    start_date="2019-10-01",
    end_date="2019-10-31",
    ch_details=True,
    output_txt=True,
    output_file="000175_2019_October_Data.txt"
)

RWD files

Convert a folder of RWD files to Text with Symphonie Data Retriever

from nrgpy.convert_rwd import local
file_filter = '0434201902' # for Feb 2019 files from site 0434
rwd_directory = 'C:/Users/[user]/rwd/'
out_directory = 'C:/Users/[user]/txt/'


converter = local(file_filter=file_filter, rwd_dir=rwd_directory, out_dir=out_directory)
converter.convert()

Convert a folder of RWD files to Text with Symphonie Data Retriever on Linux

from nrgpy.convert_rwd import local
rwd_directory = '/home/user/datafiles/rwd'
out_directory = '/home/user/datafiles/txt'
wine_directory = '/home/user/prefix32/drive_c/' # path to wine's "C:\" drive


converter = local(file_filter=file_filter, 
                  rwd_dir=rwd_directory, 
                  out_dir=out_directory,
                  wine_folder=wine_directory,
                  use_site_file=False # set to True to use site files
                  )
converter.convert()

You can also convert a single file with SDR, and save it in the same directory:

from nrgpy.convert_rwd import local
filename = '/path/to/file'
converter = local(filename=filename)

Read TXT files exported from RWD files

from nrgpy.txt_utils import read_text_data
dt = 'rwd'
txt_file = '/path/to/file.txt'
reader = read_text_data(data_type=dt, filename=txt_file)

or concatenate a whole lot of files:

dt = 'rwd'
txt_dir = '/path/to/text/files'
file_filter = 'text_in_filenames_you_want'
reader = read_text_data(data_type=dt, txt_dir=txt_dir, file_filter=file_filter)
reader.concat()

Spidar files

Spidar Vertical Profiler remote sensors generate archived csv data files.

CSV archived in a Zip format.

These can be read directly into the spidar_txt_read method. See the docstring in spidar_txt.py for more information.

Eg.

In [1]: from nrgpy.spidar_txt import spidar_data_read

In [3]: reader = spidar_data_read(filename=fname)
