GNOME desktop thumbnailer for MRC2014 (.mrc) and EM (.em), common cryo-electron tomography file formats. The thumbnail shows central slice and automatically applies contrast stretching.
Update 22.12.2021: Added support for .em files, renamed the project.
Tested on Ubuntu/PopOS 20.04, 20.10, 21.04, 21.10.
- Quit all Nautilus processes:
nautilus -q- Even if you currently do not have any Nautilus windows open, you should run the command above!

git clone git@github.com:the-lay/mrc-em-gnome-thumbnailer.git tomo-thumbnailer - Change directory:
cd tomo-thumbnailer - Run make install:
sudo make install- The script uses PIP to install necessary python packages. If you do not have system-wide pip installation,

sudo apt install python3-pip.

Most likely it is a problem with bubblewrap

and many more threads online). The short workaround fix would be to install a bwrap wrapper in /usr/local/bin:
sudo wget -O /usr/local/bin/bwrap https://raw.githubusercontent.com/NicolasBernaerts/ubuntu-scripts/master/nautilus/bwrap
sudo chmod +rx /usr/local/bin/bwrap
I strongly do not recommend this workaround. Instead, consider updating to the latest version of Ubuntu, where this issue is already fixed.
