Announcing the new Scientific Community Image Forum!


LOCI and the Broad Institute Imaging Platform are excited to announce that very soon, the ImageJ forum and CellProfiler forum will combine into a new Scientific Community Image Forum!

Who? Several open source software projects have pledged to use this forum as their recommended discussion channel henceforth—including ImageJ, Fiji, CellProfiler, scikit-image, Cytomine, Ilastik, BoneJ, and Icy. Discussion of any software packages in the imaging ecosystem is equally welcome, and other software projects are warmly invited to join this effort—the goal here is inclusivity. The NEUBIAS consortium is also a partner, and will use this forum as the central place for their “Call4Help” system. We will be presenting a poster about the new forum at the upcoming NEUBIAS conference in January.

Why? The goal is to bring the community closer together, improving the cross-visibility of these projects. It will enable scientists to ask “how do I do X?” without prior knowledge of these various software programs, give them access to a wider breadth of experts on various softwares, and make searching for previous discussions simpler. It will also educate software developers on the capabilities of the various projects being discussed, so that they can improve the links between tools, and develop features that are more likely to be novel.

Where? The URL will be We also registered for those who prefer traditional domain suffixes.

When? Our current timeline is to make the transition on January 16th. The forums may be offline for several hours on the day of transition. We will post any updates to the timeline here.

What? The forum’s focus will be on discussion of software-oriented aspects of scientific imaging, particularly (but not limited to) image analysis, processing, acquisition, storage, and management of digital scientific images. Our objective will be to foster independent learning.

How? All existing ImageJ and CellProfiler forum data will merge. Redirects from the old URLs will be installed, so that existing links will continue to work. All existing ImageJ topics will be tagged with #imagej, and all existing CellProfiler topics will be tagged with #cellprofiler.


  • What if the traffic is too much? Discourse has an excellent tagging system, so that topics can be organized non-hierarchically. E.g., if you ask a question about calling ImageJ from CellProfiler, you can add the imagej and cellprofiler tags. This will help people to narrow the scope of their attention as needed based on their time and interest. The front page will include a toplevel link to the tag feed of each partnered software project.

  • What about hardware questions? While the primary focus is on software, sometimes discussion needs to touch on both, and the line between them is not always well-defined. So the current plan is to create a category for relevant hardware discussion as well.

  • What about commercial software? Discussion of how to solve scientific problems with commercial software is very welcome, as long as it encourages independent learning. Here is an excerpt from the current ImageJ Guidelines explaining the philosophy about this:

    Our community is structured to foster not only scientific independent thinking, but just as importantly, independent learning. The open source process enables this sort of learning thanks to its accessibility, transparency, and reproducibility.

    Posts highlighting solutions besides ImageJ, both commercial and non-commercial, are very welcome here. This forum is a place to expand community knowledge and expertise. However, it is critical that these responses:

    • Offer concrete details on how the software helps users achieve the workflows being discussed.
    • Encourage knowledge and understanding of the scientific analysis process, including its principles, applications and pitfalls.
    • Do not promise users commercial support in lieu of such knowledge and understanding.
    • Do not simply highlight a particular software package as being “good at solving your problem” without further explanation or justification.

    In short: please keep your posts educational, not advertorial!

  • Other questions? Please respond here! :smile:

We will continue updating this thread as the process continues.

Many thanks!

Suggestion for reminders while creating topic or new post?

The migration has been delayed until later this month. We will post here again as soon as more details emerge.


Digest notifications

The migration is now scheduled for tomorrow, Friday, January 19. The forum may be down for several hours. We will do our best to minimize it.


Migration is imminent. If you are working on any lengthy forum posts, please save your work externally just in case. Expect everything here to be replaced with a maintenance page within the next few minutes.


Unfortunately, the migration failed—some topics from this forum were not imported into the new combined forum correctly. The Discourse team is investigating, and we will try again soon, probably next week some time.

In the meantime, the ImageJ Forum is once again open for business! :slight_smile:


I just received three identical eMails on my usually hidden Forum-eMail account:

Subject: [CellProfiler] [PM] Akismet has temporarily hidden your post

January 19


Our automated spam filter, Akismet, has temporarily hidden your post in Untangle worms training error for review.

A staff member will review your post soon, and it should appear shortly.

We apologize for the inconvenience.

(I never had anything to do with cellprofiler.)

What is going on here?



I do not know. Should be safe to ignore these mails, and apologies for the noise.


Another trial:


Unfortunately, our second attempt to migrate the forum was unsuccessful.

We are painfully aware that this extended downtime is burdensome for the community. So firstly, we apologize. It will be some time (likely months) before a third attempt is made. The silver lining is that the ImageJ Forum will remain accessible for the near future! :sunny:

The reason for the delay is technical: after completing the migration this time, we discovered that too much information was lost. Topic tags did not carry over, nor did user likes, bookmarks, or read status. We felt it would be too disruptive to the community to lose this information.

We are still dedicated to creating a unified forum for scientific image discussions, and using that forum for discussion of software including ImageJ, CellProfiler, and many others. We will continue to pursue this goal. The plan is to develop a new migration tool capable of merging two Discourse forums more comprehensively. Once such a tool is functional, we will make another attempt to create with all CellProfiler and ImageJ data preserved.
