clophfit

ClopHfit

This package provides a command line interface for fitting pH titration or binding assay data for macromolecules, such as fluorescence spectra. With this tool, users can easily analyze their data and obtain accurate fitting results.

• Version: "0.12.0"

Installation

You can get the library directly from PyPI using pip:

pip install clophfit

Alternatively, you can use pipx to install it in an isolated environment:

pipx install clophfit

To enable auto completion for the clop command, follow these steps:

1. Generate the completion script by running the following command:

   _CLOP_COMPLETE=bash_source clop > ~/.local/bin/clop-complete.bash
   

2. Source the generated completion script to enable auto completion:

   source ~/.local/bin/clop-complete.bash
   

Usage

You can check out the documentation on https://darosio.github.io/ClopHfit for up to date usage information and examples.

CLI

ClopHfit provides several command line interface tools for fitting and processing data.

prtecan

Extract and fit titrations from a list of Tecan files collected at various pH or chloride concentrations:

ppr -o prova2 --is-ph tecan list.pH --scheme ../scheme.txt --norm
    --dil additions.pH --Klim 6.8,8.4

Use the --no-weight option to reproduce an older pr.tecan version.

eq1

Predict chloride dissociation constant K_d at a given pH:

clop eq1 --help

prenspire

Parser for EnSpire (PerkinElmer) file:

ppr -o folder enspire file.csv

Destination folder (default: "./Meas-${version}") will contain for each Measurement:

• a table (csv) in wide tabular form e.g. <lambda, A01, ..., H12>;
• corresponding graphical (png) representation of spectra from all wells.

By adding a note.csv file:

ppr -o folder enspire file.csv note.csv

destination folder (default: "./Meas-${version}") will also contain:

• a pdf for each titration and label;
• a pdf for global (multiband) analysis pdfalong with global and all_SVD;
• a pdf for SVD analysis of all concatenated spectra.

note_to_csv

note_to_csv -t 37.0 -l "B E F" -o 37 NTT-G03-Cl_note
note_to_csv -t 20.0 -l "A C D" -o 20 NTT-G03-Cl_note
cat 20 37 > G03_Cl_note.csv

Python

ClopHfit can be imported and used as a Python package. The following modules are available:

clophfit.prenspire - parser for EnSpire (PerkinElmer) files
clophfit.prtecan - perform fitting of pH titration or binding assay data
clophfit.binding - perform fitting of macromolecule binding assay data

To use clophfit in your python:

from clophfit import prenspire, prtecan, binding

Features

• Plate Reader data Parser.
• Perform non-linear least square fitting.
• Extract and fit pH and chloride titrations of GFP libraries.
  • For 2 labelblocks (e.g. 400, 485 nm) fit data separately and globally.
  • Estimate uncertainty using bootstrap.
  • Subtract buffer for each titration point.
  • Report controls e.g. S202N, E2 and V224Q.
  • Correct for dilution of titration additions.
  • Plot data when fitting fails and save txt file anyway.
