niicat

This is a tool to quickly preview nifti images on the terminal. This can be helpful if you are working on a remote server via SSH and do not have a -X connection. It uses libsixel to display the images. Niicat can also display png, jpg or similar images.

Install:

pip install niicat

Usage:

niicat T1.nii.gz

Possible problems

If nothing is displayed check if your terminal supports sixel.

Per default niicat is trying to use libsixel-python. If this is causing problems you can also try using niicat with the option -ic if you are using iterm2 (this will use imgcat from iterm2) or with the option -lb (this will use libsixel-bin which can be installed via sudo apt install libsixel-bin).

Niicat was only tested on python >= 3.5.
