Hi Tal, Please see these earlier posts about what to try when the calculation is large: <https://www.rbvi.ucsf.edu/pipermail/chimerax-users/2023-April/005119.html> <https://www.rbvi.ucsf.edu/pipermail/chimerax-users/2023-April/005120.html> Otherwise, I don't have any suggestions except to say that you can specify a results directory or folder. If any of the intermediate results are written to files (and I do not know if they are), they would appear in this directory. If you are using a recent version of ChimeraX, the AlphaFold tool will have an Options button, and clicking it will show further settings including "Results directory." For details see the help: <https://rbvi.ucsf.edu/chimerax/docs/user/tools/alphafold.html> <https://rbvi.ucsf.edu/chimerax/docs/user/tools/alphafold.html#predict> Best, Elaine ----- Elaine C.

Dear all,
I am trying to use ChimeraX to predict the structure of a dimer as part of my Master’s thesis. I was able to produce a model of the monomeric structure without issue have not been able to do the same for the dimer. I am currently subscribed to Colab Pro so had assumed that the 15.0GB GPU RAM would be sufficient. The structure is 1361 amino acids long but AlphaFold2 is still able to produce the first two models successfully. However, I have not been able to produce any iterations past this stage. Any guidance on how to complete the model would be much appreciated! Alternatively, I would also be glad to extract the output of the first two models (e.g. .pdb files, plDDT plots, PAE plots, MSA heatmaps) but because the prediction does not run to completion I don’t know how to access/extract these.
I have really enjoyed using the program and hope to include the structure of the dimer in my thesis before I submit in three weeks’ time.
Many thanks,
Tal
