WG 2 – Detection system performance

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.

After the usual short organisational matters and news section, we started right away with an overview over the work done on our protocols collection since the last meeting.

There have been done updates to the figures and figure legends, and all links have been checked and updated. All authors gave their consent to their respective authorship, author order, and listed contributions. Author contributions and funding are listed in each protocol via two respective pdfs in the acknowledgment section. In addition, we looked at an example protocol run including how to add comments, to see the difference between viewing a protocol versus running it.

Subsequently, we went through the collection and all protocols to have a last check of the respective content. Several small but significant changes were made. An exhaustive list of this changes can be found in our meeting minutes. We agreed to collect and save all images and figures used for the protocols on the QUAREP-LiMi cloud. A folder will be set up for this in the WG2 work done folder.

At 6:20 PM we did publish our protocols collection. You can find the titles and DOI links below.

After this great achievement we had the pleasure of welcoming our new member Nicolas Stifani from Montreal.

For finalising our other current major project, the NBO-Q camera model and glossary, there are four meetings scheduled in January. There will be a detailed report about this project in the February meeting. In addition, in the next meeting we will take time to discuss the next steps and goals for our future WG2 work.

We started the meeting with a short discussion about our meeting day, time, and length of the meeting. In the end we decided to keep the current scenario of meeting each second Monday of a month for 90mins from 5:00 – 6:30 PM CET. This discussion was followed by a short report from the last two QUAREP-LiMi SC meetings. The main message for us was that the SC approved of our request to publish our protocols collection. This approval included the conditions that we solve all open comments and clarify author contributions following the CreDiT taxonomy. It was suggested to us to add a document to each protocol with the respective author’s contribution list. The reminder of the meeting we used to go through the comments at the collection, the protocol 1. introduction, had a quick look at the protocol 2. – Sample Preparation, and started going through the comments of protocol 3. Data Generation – Systems with Area Detector. Since there were quite a few very helpful last minute comments, we did not manage to finish going through the protocols. We are still aiming to finish and publish before the holiday season. Therefore, we decided to meet again this week Thursday, December 12th, from 4-5PM CET in the WG2 zoom room. Everybody is welcome to join.

At the end of the meeting we briefly talked about the current status of the NBO-Q camera model and glossary project. We finished the series of meetings revisiting the hardware part of the model after the first change updates. The latest changes are being added to the model. The debriefing group is working on preparing the settings part of the model. Another stakeholder meeting series will be organised for January 2025.

We closed the meeting by having a quick look at the list of To Do’s for next year.

After the usual short organisational matters and news section, we started our meeting with the presentation by David Grunwald about his soon to be published MetaMax manuscript. MetaMax is a tool hat can be used for detector calibration. The main request from David is to check if there is any input from our WG2 work that needs to be acknowledged. You can find the manuscript and a document for your comments in our 46th meetings folder.

Next Britta presented a request from WG1 to review version 3 of its protocol on measuring illumination power and stability. Version 3 now contains also measurement requirements for multi-photon systems. In addition, it has an improved table of contents and its text was modified for clarity and accuracy. Please give comments, feedback, and endorsement directly in protocols.io until end of November.

The NBO-Q camera model ad glossary is planned to be finished by the end of this year. To achieve this, three new stake holder meeting dates were announced (Nov 11th, Nov 22nd, Dec 4th). A lock-in meeting to prepare the settings part is planned on Dec 4th. Please watch out for the invitation emails.

The main part of our meeting was again dedicated towards finalising our WG2 protocols collection. We got several helpful and positive comments from WG2 members and also members from other WGs. The most urgent comment was for us to clarify our aim 1. We discussed this and agreed on a version. For the reminder of the meeting we split into two break out rooms to work on the collection, protocols 1 (introduction) and 5 (analysis) in one room and protocols 2 (sample prep) and 3 and 4 (data collection) in the other room. Since we did not manage to finish, we agreed to have extra meetings to work on the protocols (see meeting minutes for exact dates and time). Our aim is to present the final collection to the steering committee on December 3rd for approval to publish.
