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.
Working Group 3
Working Group 4
19th meeting, 20th of September 2022
Meeting date
20/09/2022 @ 5:00 PM (CET/CEST)
Meeting summary
Discuss the transition of the protocol to protocols.io. Members of WG4 are invited to put comments to keep developing the protocol for WG4 via protocols.io. Discussion on data/metadata management and the use of a microscopy image database (e.g. OMERO) in the future to progress faster. Discussion on data analysis strategies and sharing the results with AirTable and/or spreadsheets.

Working Group 7
20th meeting, 20th of February 2023
Meeting date
20/02/2023 @ 5:00 PM (CET/CEST)
Meeting summary
During the meeting we discussed the following items:
1) Next meeting will be held on March 20th 2023 and then we will continue every two months on the 3rd Monday.
2) Reminders will be sent 1 month, 1 week, 1 day, and 1 hour before each meeting.
3) The work of the WG will continue to concentrate on revising the 4DN-BINA-OME Microscopy Metadata Model and, as much as possible, will attempt to maintain compatibility with REMBI as a high-level set of recommendations.
4) WG7 works to collect the requirements of all WGs and create a consensus that incorporates the metadata requirements of all other WGs. As such WG7 works as an underlying platform on which all other WGs can build. It is important that we do a better job to explain to the QUAREP’s community that our work should be conceived as spanning across multiple WGs.
5) We need a general map of all components of the model, how they relate to each other, and which is the responsibility of which WGs
6) WG7 would like to have time during the annual meeting to discuss with everyone on this!

Meeting summary
Caterina reported that all the to-do items from last meeting have been completed. Created a granular task list based on what are tasks identified in each of the Sub-Groups and a link to spreadsheet was added to WG7 mainpage. In addition a proposal was tabled to announce QUAREP-WG7 meetings on Image.sc and it was agreed at the meeting. Ken reported the OME-Meeting on Metadata. Josh’s talk can be found here https://www.openmicroscopy.org/events/ome-community-meeting-2022/ · Great material for advocating about the need of a NG Metadata framework, although no clear definition of storage location. There were much discussion of Nature Methods and Nature Cell Biology request to QUAREP-LiMi to develop a light microscopy checklist for Nature Portfolio. Caterina reported back that we had initial meeting with Rita and Melina to discuss Nature requirements and initial meeting with WG7, 9, 11 and 12 chairs to dicuss next steps. We aim to provide the checklist by Christmas to Nature Methods. Nature is not going to release the data, but something that they will like to work and discuss with their editors.

Working Group 11
18th meeting, 9th of February 2023
Meeting summary
In order to get the finalized draft, we agreed on having the next meeting in two weeks. We will meet on Thursday Feb 9th at 11 am EST, 5pm CEST.
We will start our discussion from the “Detectors” section. The only homework assigned to you is to read the current checklist document and start thinking about how you feel about the metadata items to be ready to have another great discussion.
We will work on the checklist, but we will update the mind map too.
