tasvisan 0.1.6

Toolkit for data reduction, normalization, combination, visualization and analyis of triple-axis spectrometers, especially for Tapain and Sika

TasVisAn

TasVisAn is a Python library for data reduction, visualization, and analysis of neutron triple-axis spectrometers (TASs), particularly for the thermal-neutron triple-axis spectrometer Taipan and cold-neutron triple-axis spectrometer Sika at Australian Centre for Neutron Scattering, ANSTO. It can also be used for other triple-axis spectrometers in other facilities, for example, the thermal-neutron triple-axis spectrometer BT7 and the cold-neutron triple-axis spectrometer BT4 at NIST. More triple-axis spectrometers will be supported soon.

Install name: tasvisan
Import name: tasvisan

🚀 Installation

pip install tasvisan

📦 Usage

import tasvisan

# Example usage
# (replace with real functionality)
result = tasvisan.do_something()
print(result)

Run the GUI, Go to terminal:

#run python in terminal
>python
#in the prompt of python
>>import tasvisan
>>tasvisan.gui.TASDataBrowser.main()
>>

On linux like Ubuntu and Linuxmint, if you have warning like this:

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-user'libGL error: glx: failed to create dri3 screenlibGL error: failed to load driver: virtio_gpu python

add the following lines in your .bashrc

# Ensure always render the GUI using software
export LIBGL_ALWAYS_SOFTWARE=1

# Ensure XDG_RUNTIME_DIR exists for third-party apps
if [ -z "$XDG_RUNTIME_DIR" ]; then
    export XDG_RUNTIME_DIR=/tmp/runtime-$USER
    if [ ! -d "$XDG_RUNTIME_DIR" ]; then
        mkdir -p "$XDG_RUNTIME_DIR"
        chmod 0700 "$XDG_RUNTIME_DIR"
    fi
fi

then run

source ~/.bashrc

Then, you can rerun the GUI interface in python again.
