Hi,
I am trying to install Prosit-TMT on my local Linux machine. I downloaded the model files for TMT model but there is no config.yml file. I tried copy the config.yml from your 2019 model file package but encountered errors while running the Prosit service. Looks like the config.yml is not compatible. Could you provide the correct config.yml files for iRT and fragmentation models?
The config.yml files were provided and are available for download at
https://figshare.com/projects/Prosit_TMT_-_Model_-_Fragmentation/128438
https://figshare.com/projects/Prosit_TMT_iRT_-_Model/128432
However, even with model files, it looks like the Prosit code here on Github is not compatible with the TMT model. The TMT model requires fragmentation as an additional input but the public code here only handles/encodes sequence, charge state, and collision energy.
Would you be able to provide the Prosit code that is compatible with the TMT model so I could run it on my local machine?
Thank you very much!!

I'm also interested in the updated source code to run this model.
@cctsou - did you try to implement the missing code?

No I didn't. I am still hoping that the Prosit team will update the codes so we could use it on our local machine.

@cctsou Thanks for replying. Let's hope but I have my doubts about this.
I inspected the fragmentation model this morning (https://figshare.com/projects/Prosit_TMT_-_Model_-_Fragmentation/128438).
It seems that the provided model.yml and the model weight hdf5 files don't match.
The weight file has these fields:
['activation', 'add_meta', 'collision_energy_in', 'decoder', 'dense_19', 'dropout_28', 'dropout_29', 'dropout_30', 'embedding', 'encoder1', 'encoder2', 'encoder_att', 'fragmentation_type_in', 'meta_dense', 'meta_dense_do', 'meta_in', 'multiply_10', 'out', 'peptides_in', 'permute_19', 'permute_20', 'precursor_charge_in', 'repeat', 'timedense']
model.yaml refers to dropout_18 and other fields which are not in the weight file.
I guess we need fixed model files too...

updated the model file now it has the same fields as the weight file.

I was able to build the server with TMT model files, but then I encountered the following error by running a small peptide list as a csv file:
modified_sequence,collision_energy,precursor_charge,fragmentation

I believe that the error was because "fragmentation" was not parsed in the input data frame, I tried adding "fragmentation" into the csv parsing function below but I do not know how fragmentation is encoded. Could you please help? Could you provide the Prosit codes that are fully compatible with the TMT models you provided?
def csv(df):
df.reset_index(drop=True, inplace=True)
assert "modified_sequence" in df.columns
assert "collision_energy" in df.columns
assert "precursor_charge" in df.columns
data = {
"collision_energy_aligned_normed": get_numbers(df.collision_energy) / 100.0,
"sequence_integer": get_sequence_integer(df.modified_sequence),
"fragmentation": df.fragmentation,
"precursor_charge_onehot": get_precursor_charge_onehot(df.precursor_charge),
"masses_pred": get_mz_applied(df),
}
