Hi, Apologies if this already came up and I missed it. I just ran a few dimer models on the Chai Discovery website (https://lab.chaidiscovery.com/dashboard) and it seems to work quite well. However, when I tried to upload the relevant json file using the Structure Prediction - AlphaFold Error Plot pulldown menu, ChimeraX failed to recognize the file. I tried a few other files and something similar happened. Do you know of a workaround or is this something that is likely to get patched soon? I should mention that Chai may be putting the relevant PAE information into a “npy" file, (e.g., pae.model_idx_0.rank_1.npy) based on the size of that file, and I haven’t yet tried to convert npy to a json or know if that’s even possible. I also wonder if Boltz-1, another AF3 competitor, will have different outputs as well. They don’t seem to have a GUI yet and perhaps they won’t, so I haven’t been able tyo test this yet. I assume this has all been topic of discussions at ChimeraX though… Thanks in advance for your help! David David S.
