Library to parse and process of Nanoscope Dimension AFM files

Project Description

Nanoscope is a library to handle parsing and processing of Veeco Nanoscope Dimension AFM files. Currently hard-coded to only work for version 0x05120130 since that is what I have access to for testing, but it will likely work on newer versions.

Features

The current featureset includes:

  • Read raw Nanoscope files and image data (height, amplitude, phase)
  • Calculate standard summary information (RMS Roughness, Z-range, etc.)
  • Output the image in a Pillow-compatible format for saving
  • Data is cached after individual process steps to avoid unneeded reprocessing

Installation

Nanoscope can be easily installed using pip.

$ pip install nanoscope

Usage

An example of typical usage is shown below, including using Pillow to save the image to png and printing Z-range and RMS data to the console

import nanoscope
from PIL import Image

p = nanoscope.read('./file.000')
p.height.process()
print(p.height.zrange, p.height.rms)
pixels = p.height.colorize()
Image.fromarray(pixels).save('file.png')

The various image types can also be looped through using an iterator when processing, and the settings of the processing steps customized

import nanoscope

p = nanoscope.read('./file.000')
for img in p:
    img.process(order=2)  # flatten the image using second-order function
    print(img.type, img.rms)

The processing steps can also be called individually if needed

import nanoscope
p = nanoscope.read('./file.000')
p.height.flatten()  # flatten the image, defaults to first-order flatten
p.height.convert()  # convert the raw data to scaled values
