PeakPo 7.11.1

X-ray diffraction analysis for high pressure science

PeakPo

PeakPo is a Python application for X-ray diffraction analysis of samples at high pressure and high temperature.

Major features include:

• Pressure and temperature estimation
• Phase identification
• Two-dimensional data analysis
• Visual equation-of-state fitting
• Peak fitting
• Visual unit-cell fitting
• Generation of Excel files containing all calculation results

How to install

For PeakPo 7.10.x, use a separate environment from PeakPo 7.9.x.

If you already installed PeakPo 7.9.x with pip in an environment named peakpo, rename that environment to pkpo709 first:

conda create -n pkpo709 --clone peakpo -y
conda remove -n peakpo --all -y

Then create a new environment for PeakPo 7.10.x:

conda create -n pkpo710 python=3.11 -y

Activate pkpo710:

conda activate pkpo710

Install PeakPo 7.10.x:

python -m pip install --upgrade pip
python -m pip install peakpo

Upgrading from 7.9.x to 7.10.x

PeakPo 7.9.x is based on PyQt5, while PeakPo 7.10.x is based on PyQt6.

Because of this Qt transition, do not upgrade in-place in your old 7.9.x environment. Keep 7.9.x in pkpo709, and install 7.10.x in pkpo710.

Recommended setup:

conda create -n pkpo709 --clone peakpo -y
conda remove -n peakpo --all -y
conda create -n pkpo710 python=3.11 -y
conda activate pkpo710
python -m pip install --upgrade pip
python -m pip install peakpo

Use environments like this:

conda activate pkpo709   # old 7.9.x
conda activate pkpo710   # new 7.10.x

How to upgrade

Upgrade inside the target environment:

conda activate pkpo710

python -m pip install --upgrade --upgrade-strategy eager peakpo

How to reinstall

Reinstall inside the target environment:

conda activate pkpo710

python -m pip install --force-reinstall peakpo

How to run PeakPo (pip install)

Activate the environment where peakpo is installed:

conda activate pkpo710

Run PeakPo:

peakpo

If the peakpo command is not found, run:

python -m peakpo
