Import/export projects
######################
This tutorial shows how to import and export single-particle and tomography projects. ``nextPYP`` supports importing **Sessions**, **CLI projects**, or `Relion 4.0 `_ projects. We will demonstrate how to import/export data to and from Relion (the other options work similarly).
1. Import single-particle projects
==================================
* Create or navigate to an existing single-particle project, click :badge:`Import Data,badge-primary` and select :badge:`Single-particle (from Star),badge-primary`
* Go to the **Import parameters** tab:
.. tabbed:: Import parameters
- Set the location of the ``Relion refinement star file`` by clicking on the icon :fa:`search,text-primary` and browsing to the corresponding directory
- Set the location of the ``Relion motioncorr star file`` by clicking on the icon :fa:`search,text-primary` and browsing to the corresponding directory
- Set the location of the ``Relion project path`` by clicking on the icon :fa:`search,text-primary` and browsing to the corresponding directory
* Go to the **Raw data** tab:
.. tabbed:: Raw data
- Set the ``Location`` of the raw data by clicking on the icon :fa:`search,text-primary` and browsing to the corresponding directory
- Click on the **Microscope parameters** tab
.. tabbed:: Microscope parameters
- Set ``Pixel size (A)``
- Set ``Acceleration voltage (kV)``
* (optional) Set parameters in other tabs
* Click :badge:`Save,badge-primary` and the new block will appear on the project page
* Click :badge:`Run,badge-primary` followed by :badge:`Start Run for 1 block,badge-primary` to launch the import process
* Click inside the block to inspect the results
2. Import tomography projects
=============================
* Create or navigate to an existing tomography project, click :badge:`Import Data,badge-primary` and select :badge:`Tomography (from Star),badge-primary`
* Go to the **Import parameters** tab:
.. tabbed:: Import parameters
- Set the location of the ``Relion refinement star file`` by clicking on the icon :fa:`search,text-primary` and browsing to the corresponding directory
- Set the location of the ``Relion tomogram star file`` by clicking on the icon :fa:`search,text-primary` and browsing to the corresponding directory
- Set the location of the ``Relion project path`` by clicking on the icon :fa:`search,text-primary` and browsing to the corresponding directory
* Go to the **Raw data** tab:
.. tabbed:: Raw data
- Set the ``Location`` of the raw data by clicking on the icon :fa:`search,text-primary` and browsing to the corresponding directory
- Click on the **Microscope parameters** tab
.. tabbed:: Microscope parameters
- Set ``Pixel size (A)``
- Set ``Acceleration voltage (kV)``
- Set ``Tilt-axis angle (degrees)``
* (optional) Set parameters in other tabs
* Click :badge:`Save,badge-primary` and the new block will appear on the project page
* Click :badge:`Run,badge-primary` followed by :badge:`Start Run for 1 block,badge-primary` to launch the import process
* Click inside the block to inspect the results
3. Export single-particle/tomography projects
=============================================
* Choose an existing :badge:`Particle refinement,badge-primary` block, click on the menu icon :fa:`bars, text-primary` and select the :fa:`edit, text-primary` Edit option
* Go to the **Export** tab:
- Check ``Export metadata``
- Set the location of the ``Input parfile`` you want to export by clicking on the icon :fa:`search,text-primary` and browsing to the corresponding directory
* Click :badge:`Save,badge-primary`
* Click :badge:`Run,badge-primary` followed by :badge:`Start Run for 1 block,badge-primary` to launch the export process
Once the job ends, the results will appear in the specified folder and will be ready to import into other packages. For a tomography project example, you can use `Relion's Import Coordinates `_ procedure
