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.

28th meeting, 13th of March 2023
Meeting date
13/03/2023 @ 5:00 PM (CET/CEST)
Meeting summary
- First we discussed some general QUAREP-LiMi news:
- QUAREP-LiMi is now a community partner of image.sc, we potentially need to contribute to the moderating in the future
- there is a community room at ELMI for QUAREP and other imaging communities to do 6 workshops, WG2 member contribution is welcome
- the French MetrologyJ-QC group is very interested in a collaboration with us in WG2, we will invite them to a future WG2 meeting
- WG12 paper is in the review process of Nature methods
- Second we collected ideas on which topics to discuss in the breakout room. It was agreed to especially include open questions and problems: challenge how to measure sensitivity; our strategy of community roll-out; current problems we are facing: UUIDs; data handling, storage, and retrieval. We also collected some potential survey questions. A small team was formed to prepare the breakout room, the short introduction video and questions for a possible survey; all of which will be presented during our next WG2 meeting.
- Third followed the reports from the small group measurement teams: for sample preparation, we now have the text for the marker-pen sample on protocols.io (please check it out). A text is planned for the Chromaslide ramp. MathiasH went to the EMVA1288 certification course. He will report in our next meeting.
27th meeting, 13th of February 2023
Meeting date
13/02/2023 @ 5:00 PM (CET/CEST)
Meeting summary
After first talking about organisational news, we discussed the changes in date and plans for our upcoming QUAREP-LimI general assembly meeting. It is going to be held online on April 26th 2023 3-6PM.
We decided that we want to participate with our own breakout room and formed a small preparation team which will also think about potential questions for a survey. A short video presentation needs to be prepared as well.
Next the small measurement teams reported their results. Team CET focussed on test samples and found the marker pen as bright enough, easy to prepare and use.
Team CET2 focused on the protocol and its usability via protocols.io. There is still a lot of optimization to do (changing the order of the steps, optimizing the run behavior of the protocol).
This discussion was followed by the report from our training session with Emma Ganley from the protocols.io team.
At the end of the meeting we summarized the main next steps: simplify our protocols and the protocols structure, and updated our detection system behavior measurement excel sheet.
The APE measurement reporting session is planned for our June meeting.
26th meeting, 9th of January 2023
Meeting date
09/01/2023 @ 5:00 PM (CET/CEST)
Meeting summary
We used the opportunity of this being the first meeting in 2023 to look back at our achievements, but also challenges, last year.
As a main challenge we identified the motivation and organisation for collecting data and analysing it. This is essential to test and optimise our protocols to be able to finalise and subsequently publish them. We therefore decided to form small groups of 3-4 people doing the measurements together.
In addition, we discussed to have our aims and next steps smaller and more tight, focus on one aim only. This way we will steadily move forward to eventually reach our goal.
Our protocols group gave a brief update on the development of our WG2 protocols in the protocols.io QUAREP-LiMi workspace and informed about the planned training session with Emma Ganley from the protocols.io team.
At the end of the meeting we summarised the main next steps: do measurements in the small groups and contact the protocols.io support team about our needs.
25th meeting, 12th of December 2022
Meeting date
12/12/2022 @ 5:00 PM (CET/CEST)
Meeting summary
We started with a brief report from WG9&co-chairs last meeting, focusing mainly on the next general assembly meeting of QUAREP-LiMi.
In this meeting, we then had a big discussion on Metadata. There is a specific need of finding a good way to collect, name and recover image files.Try to find an agreement on naming the file isn’t universally acceptable. Therefore, the idea is to find a way to recover the most important metadata on acquisition parameters and device settings in a unique format. Omero could be the answer and it requires a list of metadata. In the same direction is also the request from Nature protocol and other editors for publication.

33rd meeting, 17th of February 2025
Meeting date
17/02/2025 @ 5:00 PM (CET/CEST)
Meeting summary
The meeting covered updates on France BioImaging’s metadata efforts, including OMERO.quay beta testing, buffer server deployment, and authentication improvements. WG10 discussed defining “raw” images and their metadata requirements, emphasizing the need for clarity on file formats. The website report highlighted the need for better organization and visibility of resources, with a proposal to create a landing page and potentially rebrand NBO-Q. Discussions on synonyms and profiles addressed term mapping challenges and possible alias extensions. Additional topics included a McGill student project porting NBO-Q to LinkML and preparations for an ISO discussion at OME2025. The next meeting date requires rescheduling due to Easter.
31st meeting, 21st of October 2024
Meeting date
21/10/2024 @ 5:00 PM (CET/CEST)
Meeting summary
The following topics were discussed:
- Report back on work done by members of the WG to align the terminology used in the upcoming WG11 checklist with NBO-Q
- Mandate from the SC to WG7 to generate an NBO-Q landing page.
- The primary target audience for the NBO-Q landing page is QUAREP members.
- The NBO-Q landing page will start by simply delineating the data model and why it is essential to the QUAREP mission. Subsequently, more content, including examples and visualizations, will be added gradually. A group of volunteers were identified to work on moving this project forward. They will present their work during the next meeting.
- In all we do, it is essential to advance together and develop consensus with all members of QUAREP. To this aim, it is crucial to educate all members of QUAREP on what metadata is, how metadata can be represented in machine and human-readable manners, and why organizing metadata in a model is essential.

Working Group 11
40th meeting, 22nd of May 2025
Meeting date
22/05/2025 @ 5:00 PM (CET/CEST)
Meeting summary
1-During the last meeting, you expressed your wish to publish the bare minimal list as a standalone document instead of the comprehensive manuscript we were initially envisioning. The main concerns we have are figuring out the type of journal that accepts this format/content and the fact that there are at least 3 publications providing guidelines/checklists for methods reporting.
2-The second action item was to organize the live document that we created a long time ago in which we determined what was level 1 (required), 2 (depends on the application), 3 (nice to have) to build a logic tree for biologists to generate the appropriate checklist depending on the experiment they did.
