Running "predict_with_crosslinks.py" with "restraints.csv --distograms" gives the error about alphalink

[BelyaevaJuly]

distr.csv should be space-separated, not comma-separated.

Are you by chance using an old version of AlphaLink? The load_crosslinks function call in your error message no longer exists and doesn't include the distogram flag. It's unfortunate, but it looks like the "paper release" commit was before the distogram flag. The code release v1.0 on the other hand should contain it. But if you can, you should update to the newest version with git pull.

One more thing, if you need to use the databases, they have to be named now, e.g., --uniref90_database_path uniref90.fasta --mgnify_database_path ... etc. see the README

We with our system administrator managed to establish a correct version you wrote above (probably).
With it, I got the following error:

stereo_chemical_props_path = os.path.join(os.path.dirname(__file__), stereo_chemical_props_path)
# loading that file with a relative path.

After that, the following code was executed successfully:

I got the following output files:

3. 'sp|P24941|CDK2_HUMAN_model_5_ptm_crosslinks_unrelaxed.pdb'

And dist.csv now really space-separated :)

There are two problems. First, you are trying to use the distogram settings with the "normal" network. If you use the --distograms flag, you have to use the finetuning_model_5_ptm_distogram.pt network weights. Second, you would need to transform your restraints.csv first into a distogram. This can be done with the preprocessing_distributions.py script, see https://github.com/lhatsk/AlphaLink#crosslinking-data

I was eventually able to run AlphaLink on the provided test example.
I will try further on my own case.

Thank you!

Dear AlphaLink developer, sorry again.

I managed to launch AlphaLink for testing case, with xl-restraints looking like (it failed in case of space-separated file): |

52,148,0.05
55,148,0.05
78,148,0.05
129,164,0.05

Now I am trying to launch code with --distograms flag.
I performed the following steps:

1. created file rest.csv:

52,148,15.0,5.0,normal
54,151,20.0,5.0,normal
124,152,25.0,6.0,normal

2. launched processing_distributions.py and obtained distr.csv:

I tried with .csv files space- or comma-separated, but got errors.
In case of space-separated distr.csv I got the following one:

Without --distograms, with "FDR xl restraints" everything works on testing example.

Could you please check again where may be the problem?

distr.csv should be space-separated, not comma-separated.

Are you by chance using an old version of AlphaLink? The load_crosslinks function call in your error message no longer exists and doesn't include the distogram flag. It's unfortunate, but it looks like the "paper release" commit was before the distogram flag. The code release v1.0 on the other hand should contain it. But if you can, you should update to the newest version with git pull.

One more thing, if you need to use the databases, they have to be named now, e.g., --uniref90_database_path uniref90.fasta --mgnify_database_path ... etc. see the README

Great! You might need to copy the stereo_chemical_props.txt file to the openfold/resources folder or if you installed it in some kind of environment to the respective folder in the environment. But setting the path directly obviously also works.
