I will try that approach... In my case the asymmetric unit is composed of trimers, in that case do i need to provide the sequence only once or as 3times?
from model-angelo.
Sequences should only ever be unique chains. The pipeline tries to remove duplicated chains but it is always best to provide it with clean data :)

Does ModelAngelo support non-cubic maps? If so, one can extract an asymmetric unit (ASU) before running the program, significantly reducing the target volume. Because a chain might go into the neighboring ASU, you might want to add some "buffer regions" around an ASU.
from model-angelo.
I also though about this.
But using e.g., PHENIX to isolate a unique map, this must not necessarily the ASU. But splitted within the polypeptide density.
I my case, I can do this, as I can validate the unique model. But for an unknown map, it would be better to identify the symmetry during the calculation, e.g., after predicting the Ca backbone.

Hi,
Thank you for using ModelAngelo.
I'm sorry, but currently ModelAngelo treats all inputs as asymmetric and builds everything separately. It might be best to give parts of the map that you think are single asymmetric units to ModelAngelo, if you wish. Also, the results from the first GNN round will be very similar to the final results. You can use the output_fixed_pruned.cif file as the final pruned output and the output_fixed.cif file as the raw unpruned output. If you are using the no sequence model, you will only have the output.cif file.

Hi Kiarash,
thank you for the fast reply. The output_fixed_aa_pruned.cif looks correct (based on the overall expectation), but instead of 24 chains, this model contains 65 chains, and the individual 24 chains are fragmented. This is ok for me, as I can deal with this, but for non-experienced users, this might be an issue.

ps. I can give you access to the map and fasta, and intermediate results privately, if this helps you to improve your code :)

Hi,
Oh, I know why that is the case. Could you share the inputs and outputs and I can take a look.
Basically, this all gets fixed up in the last step, but that takes too long for you in this case :)
Best,
Kiarash.
from model-angelo.
This is my exact use case as well. Please let me know if a suitable solution is available.
Good job though Kiarash! :)

Hi @shahpnmlab ,
Could you try to break up the map manually? That is probably best. You can still use the same FASTA file.
Best,
Kiarash.
