Working Group 1
Quality Assessment and Reproducibility for Instruments & Images in Light Microscopy
The Consortium for Quality Assessment and Reproducibility for Instruments and Images in Light Microscopy (QUAREP-LiMi), formed by the global community of practitioners, researchers, developers, service providers, funders, publishers, policy makers and industry related to the use of light microscopy, is committed to democratizing access to quantitative and reproducible light microscopy and the data generated by it.
Our mission is to provide a comprehensive set of community-agreed guidelines, protocols, automation procedures and other resources aimed at improving quality control, quality assurance, and instrument/method calibration. The stakeholders advocate for the use of the highest level of reproducibility for data generated by light microscopy methods in scientific research and biotechnology applications. In support of achieving its mission, QUAREP-LiMi:
-
sanctions Working Groups to form teams that focus on specific technical or outreach topics;
-
maintains, disseminates, and teaches best practices, protocols, and software tools; and
-
collaborates with providers of reference materials or instrumentation or other tools that enable the easy implementation of best practices at the community level.
We came together in our first online Web meeting on the 28th of April, 2020, with about 50 attendees. By now (24st of April 2024), the network has grown to 620 people from 41 countries worldwide. We have members from academia (research labs, core facilities), national microscopy communities, companies involved in the microscopy business, organizations or institutions related to standardization on a national or international level, and scientific publishers and observers from funding agencies (see the graph below and on the member page for an overview).
Ten working groups (WGs) were established in the 2nd General Meeting on the 9th of July 2020 to bring our common aims quickly forward. Our web page gives an overview of QUAREP-LiMi’s work. In the 3rd General Meeting, WG 11 “Microscopy Publication Standards” and later WGs 12 “Image Visualization and Analysis” and 13 “Phototoxicity” were established. WG 14 “Environment” and 15 “FLIM” are in the process of being established, and WG 8 is restructured to work on “Education, Training and Outreach”.
QUAREP-LiMi operates a NextCloud and an OMERO server, serving as a centralized repository and exchange point for our collective work. These platforms facilitate collaboration and data sharing among our members.
QUAREP-LiMi is absolutely open to new members, and we are looking forward to your contribution. If you are interested in joining our initiative, please fill out our membership form. Use our form for changing your working group (WG) or joining a new WG. For any further questions, please contact us.

Working Group 2
36th meeting, 13th of November 2023
Meeting date
13/11/2023 @ 5:00 PM (CET/CEST)
Meeting summary
After a short session of QUAREP-LiMi news and updates on our other running projects, we mainly focussed on our planned paper which should accompany the publishing of our protocols. We discussed main aspects, determined topics which need to be addressed and members who our responsible for working on the topics. To be able to have time to do so, we decide to skip the meeting in January 2024.

Meeting summary
LacJ shared the key points discussed during the SC meeting on 2024/10/01 and presented the work on the data model to the WG members. The group focused on discussing the organization and content of the protocol, and deadlines were set to ensure its finalization. Our next WG meeting will be on November 19th.
Working Group 5
8th meeting, 6th of May 2021
Meeting summary
WG 5 have principally been testing beads for PSF measurements, using different formats (polystyrene, DNA origami, nanodots, printed patterns). We have identified an optimal size range for confocal and widefield imaging, and a re still testing the ease of use, functionality and robustness of several of these formats. We have begun a draft methodology which we propose to publish for Confocal PSF measurement using beads before developing the method further for other modalities, as well as investigating alternative methods, such as mirrors for axial resolution tests.

Meeting summary
Paula shares that bare-minimum checklist is moving forward. It took on new momentum at BINA meeting. SC endorsed content at Oct. SC meeting. Caterina and Judith are aligning with NBO-Q schema.
Some topics have been discussed.
Decission Tree for chosing reporting structure. Paula collected input from last meeting
MicCheck tree updates. is there a way to align MicCheck with quarep work?
Can users actually answer questions at the level of MicCheck?
