hyPIRana

Analysis software development for mid-IR PiFM / PiF-IR: analysis of hyperspectral Scans (MonIRana analyses data sets of single PiF-IR spectra)

hyPIRana v1.1.0 release including newly added MonIRana

version v1.1.0 date 2025-04-08

MonIRana is a program for analysis of a set of spectral data provided in a tabulated textfile This code has been developed to analyze single spectral dataset from mid-IR Photo-induced Force Microscopy (PiF-IR) Contributions in this code so far have been made by: Mohammad Soltaninezhad, Sebastian Unger, Maryam Ali, and Daniela Täuber.

monIRana can do:

• Calibration
• Calculate mean spectra of the complete data set
• Run a PCA on the data set and provide plots of results
• Clustered presentation of Amide rich & glycan rich analyzed spectra

The available raw data in this repository are for:

• Calibrated PiF-IR spectra for treated Bacillus Subtilis (classified to Amide rich & glycan rich spectra)
• Calibrated PiF-IR spectra for untreated Bacillus Subtilis (control) from the same experiment

This sofware is part of hyperspectral analysis methods used in the published article: "Nanoscale chemical characterization of secondary protein structure of F-Actin using mid-infrared photoinduced force microscopy (PiF-IR)" by Jesvin Joseph, Lukas Spantzel, Maryam Ali, Dijo Moonnukandathil Joseph, Sebastian Unger, Katharina Reglinski, Christoph Krafft, Anne-Dorothea Müller, Christian Eggeling, Rainer Heintzmann, Michael Börsch, Adrian T.

Contributions in this code so far have been made by Sebastian Unger, Maryam Ali, René Lachmann, Rainer Heintzmann, Mohammad Soltaninezhad and Daniela Täuber. For details see headers of the code.

This code analyzes the hyperspectral data by:

• Plotting generated images: AFM Topography, integrated PiF-IR hyperspectral image, and AFM phase image.
• Plotting the mean spectrum on PiF-IR intensity.
• Principal Component Analysis PCA represented by loaded components plot, scatter plot, and individual component factor plots.

In the context of the article by Joseph et al. Spectrochimica Acta part A: Molecular and Biomolecular Sepctroscopy, 306, 123612, 2024, two PiF-IR hyperspectral data sets have been analysed using hyPIRana. The Raw data have been available in this repository:

• single-fibrillar F-Actin
• crosslinked F-Actin
