AmiAutomation 0.0.12

Package to extract binary files into pandas dataframes

Binaries extraction

This package contains the tools to easily extract binary data from PX3's:

• Heat Log
• 2 Second Log
• Wave Log
• Composite
• Histogram

Into a pandas dataframe for further processing

Usage

Importing a function is done the same way as any python package:

from AmiAutomation import PX3_Bin, LogData

From there you can call a method with the module prefix:

dataFrame = PX3_Bin.file_to_df(path = "C:\\Binaries")

or

dataFrame = LogData.binFileToDF(path = "C:\\Binaries")

LogData Methods

You can get Binary log data in a LogData format that contains useful data about the binary file, including samples inside a pandas dataframe

from AmiAutomation import LogData

#This returns the whole data
logData = LogData.binFileToDF("bin_file_path.bin")

#To access samples just access the dataframe inside the LogData object
dataFrame = logData.dataFrame 

This method can also be used to retrive the data table from inside a ".cpst or ".hist" file

PX3_Bin Methods

This method returns a single pandas dataframe containing extracted data from the provided file, path or path with constrained dates

• file_to_df ( path, file, start_time, end_time, verbose = False )

• To process a single file you need to provide the absolute path in the file argument

dataFrame = PX3_Bin.file_to_df(file = "C:\\Binaries\\20240403T002821Z$-4038953271967.bin")

• To process several files just provide the directory path where the binaries are (binaries inside sub-directories are also included)

dataFrame = PX3_Bin.file_to_df(path = "C:\\Binaries\\")

• You can constrain the binaries inside a directory (and sub-directories) by also providing a start-date or both a start date and end date as a python datetime.datetime object

import datetime

time = datetime.datetime(2020,2,15,13,30) # February 15th 2020, 1:30 PM

### This returns ALL the data available in the path from the given date to the actual time
dataFrame = PX3_Bin.file_to_df(path = "C:\\Binaries\\", start_time=time)

import datetime

time_start = datetime.datetime(2020,2,15,13,30) # February 15th 2020, 1:30 PM
time_end = datetime.datetime(2020,2,15,13,45) # February 15th 2020, 1:45 PM

### This returns all the data available in the path from the given 15 minutes
dataFrame = PX3_Bin.file_to_df(path = "C:\\Binaries\\", start_time=time_start, end_time=time_end )

Tested with package version

• pythonnet 2.5.1
