Frank AylwardAny idea what this algae or plant is? It forms green films on top if a nearby pond. Under the scope it forms largish clumps or sacks of cells- maybe 50-100 um or so across. Seems too large for most algae and too small for plants like duckweed. I've never come across it before, and I'd be curious to get an ID if anyone knew!<a href="https://genomic.social/tags/algae" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#algae</a> <a href="https://genomic.social/tags/ponds" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ponds</a> <a href="https://genomic.social/tags/microscopy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#microscopy</a>

Jonathan TownsonImage analysts: What is your go to method for batch converting image files from the proprietary format to a tiff file? If this should be done at all...I’ve been using FIJI to open and re-save mine. Although this gives me another look at the image as a QC step, I am using Napari more and more and have found a tiff easier to load into Python.<a href="https://biologists.social/tags/Microscopy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Microscopy</a> <a href="https://biologists.social/tags/ImageAnalysis" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ImageAnalysis</a> <a href="https://biologists.social/tags/Napari" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Napari</a> <a href="https://biologists.social/tags/FIJI" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FIJI</a>

sungHumble onion cells imaged using a cheap Amscope microscope and old Kodak 16mm movie film hand-spooled into a 110 cartridge. The film was developed on the spot using my standard caffenol setup.

Virgile AndreaniI spent the day rectifying segmentation and tracking for bacteria in microfluidic devices. 1000 frames, 5 chambers, ~8 cells per chamber, so 40000 pictures of cells to look at, and check that they match frame to frame. I think I'm done with screens for the day. Fortunately automation helps, and drawing the lineages as graphs allows to spot errors more easily. Now I have a clean dataset that I can analyse and also use as a training dataset for the next iteration!<a href="https://fosstodon.org/tags/microscopy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#microscopy</a> <a href="https://fosstodon.org/tags/AcademicChatter" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AcademicChatter</a>
