Fetch metadata from EPU / SerialEM and launch on-the-fly pre-processing
Project description
Still in development, but you are welcome to try!
A simple PyQt5 app to fetch acquisition metadata from EPU session or SerialEM. It parses the first found xml/mrc (EPU) or mdoc file (SerialEM) associated with a data collection session. In case of SerialEM you need to enable saving mdoc file for each movie.
Installation
The app requires python3, numpy and PyQt5 to run.
From pypi: pip install MDCatch (recommended)
From sources - you have two options:
Create python virtualenv:
python3 -m venv mdcatch source mdcatch/bin/activate git clone https://github.com/azazellochg/MDCatch.git cd MDCatch pip install -e .
Create conda virtualenv (requires miniconda3 installed):
conda create -n mdcatch python=3.8 conda activate mdcatch git clone https://github.com/azazellochg/MDCatch.git cd MDCatch pip install -e .
Configure
Relion 3.1 or Scipion 3.0 is in in your PATH
Preprocessing templates: Schedules folder for Relion, template.json for Scipion
Edit config.py to adjust it to your setup
Running
Simply type mdcatch
Working principle
The idea is to launch the app on a processing server as soon as EPU/SerialEM starts data collection and the first movie is acquired. The server has to have access to both EPU session folder and movies folder, or to SerialEM movie folder.
check if username exists in the NIS database (ypmatch username passwd)
find and parse the first xml/mdoc file, getting all acquisition metadata
create a Relion/Scipion project folder username_microscope_date_time inside PROJECT_PATH (or inside Scipion default projects folder)
create symlinks for movies, gain reference, defects file, MTF in the project folder
modify existing Relion Schedules/Scipion templates then launch Relion/Scipion on-the-fly processing
Screenshots
TODO
beam tilt is parsed but not used since we parse only a single xml/mdoc for the whole session
SerialEM conversions: gain ref dm4->mrc, defects SerialEM->Relion
use GAIN_DICT from config
