@Sajjad_Razza @ai_dragonfly I haven't used VGSTUDIO. I do most of the analysis outside of dragonfly because I often do hyperparameter optimization/ training on an hpc cluster w GPUs to speed things up. Image annotation/training/segmentation can be some directly in @ai_dragonfly. Probably similar 4 VGSTUDIO.

@JasperWubs @advancedphoton @EMSLscience @jgi @cloud_zero @ajmargenot @tamasvarga @OQafoku That little aggregate is ~500 GB of data after reconstruction. Our goal is to build the tools folks need to use these instruments like an ICP in the early days. That means not just collecting the data, but processing it into a meaningful form. I hope my response makes sense!

@JasperWubs @advancedphoton @EMSLscience @jgi @cloud_zero @ajmargenot @tamasvarga @OQafoku This is from a real soil collected in a vineyard. When I started, synchrotron based XCT took 10 minutes to image an aggregate. Now it can be done in 30 sec. Big cores (8 cm x 20 cm) take longer, but can be imaged in hrs w/ new bench XCT. Not far from tractor mounted scanners.

@DylanBeaudette Spinning the drain. There is just so much AI generated chaff, it is getting harder to trust information on the internet.

@RobertFinger1 @usys_ethzh @ETH_en @Johansix6 Why not be more forthright about the age requirement in the advertisement? Seems straight forward to say you are looking for applicants 35 years of age and under.

Do you have experience developing and applying modern deep learning approaches to image segmentation problems? Come work with @ajmargenot, @cloud_zero, and I as we use multimodal imaging to better understand how long term management changes soils at the historic Morrow plots!
@drippner and I are looking to hire a postdoc to lead X-ray CT of soils under 149 year treatments from @UofIllinois historic Morrow Plots. Machine learning image analysis to quantify and link soil pore networks with biogeochemical functions. Remote work possible. @EMSLscience
