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.

Meeting summary
Agenda
- Organizational matters and News
- QUAREP-LiMi ELMI 2025 workshop contribution
- Report from OMERO subgroup meeting
- Update on NBO-Q camera model & glossary
- Report from paper working group
- Next steps
Summary
We started the meeting with discussing our summer meeting scenario. Due to a public holiday and ELMI 2025, we decided to shift our June meeting to June 23rd. In addition, we decided to skip the meetings in July and August to have time for finishing the camera model and glossary, work on the paper, and have time for vacation. We decided to start again with the regular meeting schedule on September 8th.
This summer meeting organisation was followed by a report from the May steering committee meeting. One great news for WG2 was that the SC endorsed the terminology “dexel” for the detector element versus “pixel” as picture element. Next, we briefly discussed the current status of our ELMI workshop preparation.
This was followed by a report from the QUAREP-LiMi OMERO subgroup meeting. A naming convention was introduced by that subgroup, which everybody needs to follow. We discussed how to implement our spreadsheet terms and how to best automate the upload to OMERO. The WG2 co-chairs will look over tags and naming structure for WG2.
This discussion was followed by an update from the NBO-Q camera model and glossary group. The stakeholder group finished working on the hardware part and will now continue with the settings. The plan is to be finished by the end of this summer.
The WG2 paper working group reported from their first meeting where they summarised paper-related content from our past meeting minutes.
We finalised the meeting with summarising the next steps: finalise the NBO-Q camera model and glossary, work on our paper and collect data for it, support WG7 in their work to calibration metadata, and generalise the automation of our WG2 protocols collection to have it eventually working on all microscopy platforms.

Meeting summary
After discussing possible scenarios for our WG2 work during summer, we reported from the SC meeting on April 1st. This was followed by a detailed report from the Annual QUAREP-LiMi Meeting that took place April 10th.
The ELMI contribution preparation team reported the submission of three workshop abstracts. Approval was expected to be highly likely (by now all our submitted workshops have been accepted).
The NBO-Q camera glossary team could report that the hardware part is finished! Next, the settings part will be tackled, but is not expected to take that long. The rest of the meeting we spend on collecting topics for WG2 to work on in the future: automation for our WG2 protocols, paper to accompany our WG2 protocol collection, collect data for it, NBO-Q model update for point detectors, amongst others. For each of these topics we need to find people to take the lead and define respective time lines.

Summary
This meeting was a bit of a house-keeping meeting. After the report from the March SC meeting we briefly discusses our planned contributions to the Annual QUAREP-LiMi meeting. This was followed by setting up a time line and preparation group for organising our contribution to ELMI2025. Next, we had a quick update on the current status of our NBO-Q camera model and glossary project. We closed the meeting with discussing the next projects we need to tackle. We will first focus on preparing our paper and organising collection of data. We will also have to revisit our long-term goals as next big projects.49th meeting, 10th of February 2025

Meeting summary
This was our first meeting since the publication of our WG2 Protocols collection. Therefore, our main focus was to discuss the next steps for our work.
We agreed on a key concern: how to collect data now that the protocol is available, and how we can assist users in automating the data collection process for use with the analysis tool. We agreed to use OMERO as our main tool. However, this will require significant work. We need to have an easy way to upload data to the OMERO server. Secondly, we need to determine the metadata necessary to support the main detector parameters that can be analysed using our published protocol tools.
Secondly, we got an update on the progress of the Camera Glossary and Model work. The hardware part is almost done. This will be followed by working on the settings part.
Finally, we decided to use the exciting possibility to present our Protocols collection by offering one or two workshops in the community room during the ELMI meeting in June 2025 in Heidelberg.

Meeting date
23/04/2025 @ 4:00 PM (CET/CEST)
Meeting summary
Summary (topics discussed): Presented and discussed objectives and survey, provided feedback from GerBI, who saw the survey. Sylvia and Gaby showed the latest changes made to the survey. Asked for more contributions (links were shared again). Angela suggested also we have someone more expert on surveys go through the questions (especially making it quantifiable through better structured Likert scales?).
Once this is sorted the Gaby sends a preview of the survey to all QUAREP for final feedback, on the spirit of opening to all community before going public with results.
We ten plan for a date for releasing if and when there is consensus.
Ask also to vote on whether we can/should ask for email (as optional, never mandatory!).
