A collection of tools for painting super-resolution images. The Picasso software is complemented by our Nature Protocols publication. A comprehensive documentation can be found here: Read the Docs.
Adaptive Intersection Maximization (AIM, doi: 10.1126/sciadv.adm7765) implemented in Picasso.
To see all changes introduced in previous versions, click here.
Check out the Picasso release page to download and run the latest compiled one-click installer for Windows. Here you will also find the Nature Protocols legacy version.
For the platform-independent usage of Picasso (e.g., with Linux and Mac Os X), please follow the advanced installation instructions below.
As an alternative to the stand-alone program for end-users, Picasso can be installed as a Python package. This is the preferred option to use Picasso’s internal routines in custom Python programs. Those can be imported by running, for example, from picasso import io (see the "Example usage" tab below) to use input/output functions from Picasso. For windows, it is still possible to use Picasso as an end-user by creating the respective shortcuts. This allows Picasso to be used on the same system by both programmers and end-users.
- Open the console/terminal and create a new conda environment:
conda create --name picasso python=3.10 - Activate the environment:
conda activate picasso. - Install Picasso package using:
pip install picassosr. - You can now run any Picasso function directly from the console/terminal by running:
picasso render,picasso localize, etc, or import Picasso functions in your own Python scripts.
If you wish to use your local version of Picasso with your own modifications:
- Open the console/terminal and create a new conda environment:
conda create --name picasso python=3.10 - Activate the environment:
conda activate picasso. - Change to the directory of choice using
cd. - Clone this GitHub repository by running
git clone https://github.com/jungmannlab/picasso. Alternatively, download the zip file and unzip it. - Open the Picasso directory:
cd picasso. - You can modify Picasso code in this directory.
- To create a local Picasso package to use it in other Python scripts, run
pip install -e .. When you change the code in thepicassodirectory, the changes will be reflected in the package. - You can now run any Picasso function directly from the console/terminal by running:
picasso render,picasso localize, etc, or import Picasso functions in your own Python scripts.
Regardless of whether Picasso was installed via PyPI or by cloning the GitHub repository, some packages may be additionally installed to allow extra functionality:
pip install pyinstallerif you plan to additionally compile your own installer with Pyinstaller.- (Windows only)
pip install PyImarisWriter==0.7.0to enable .ims files in Localize and Render. Note thatPyImarisWriterhas been tested only on Windows. - To enable
GPU fitting, follow instructions on Gpufit to install the Gpufit python library in your conda environment. In practice, this means downloading the zipfile and installing the Python wheel. Picasso Localize will automatically import the library if present and enables a checkbox for GPU fitting when selecting the LQ-Method.
If Picasso was installed from PyPI, run the following command:
pip install --upgrade picassosr
Run the PowerShell script “createShortcuts.ps1” in the gui directory. This should be doable by right-clicking on the script and choosing “Run with PowerShell”. Alternatively, run the command
powershell ./createShortcuts.ps1 in the command line. Use the generated shortcuts in the top level directory to start GUI components. Users can drag these shortcuts to their Desktop, Start Menu or Task Bar.
Besides using the GUI, you can use picasso like any other Python module. Consider the following example::
from picasso import io, postprocess
path = 'testdata_locs.hdf5'
locs, info = io.load_locs(path)
# Link localizations and calcualte dark times
linked_locs = postprocess.link(picked_locs, info, r_max=0.05, max_dark_time=1)
linked_locs_dark = postprocess.compute_dark_times(linked_locs)
print('Average bright time {:.2f} frames'.format(np.mean(linked_locs_dark.n)))
print('Average dark time {:.2f} frames'.format(np.mean(linked_locs_dark.dark)))
This codeblock loads data from testdata_locs and uses the postprocess functions programmatically.
Check picasso/samples/ for Jupyter Notebooks that show how to interact with the Picasso codebase.
If you have a feature request or a bug report, please post it as an issue on the GitHub issue tracker. If you want to contribute, put a PR for it. You can find more guidelines for contributing here. We will gladly guide you through the codebase and credit you accordingly. Additionally, you can check out the Projects-page on GitHub. You can also contact us via [email protected].
