XGBoost expecting different number of features than custom model

[hspekt]

Describe the bug
Using a custom model trained by MQ > Tools > MS/MS intensity prediction errors on library prediction in MaxDIA.

The error message seems to indicate XGBoost is looking for 227 features but only finding 216.

To Reproduce
Steps to reproduce the behavior using MQ 2.6.6.0:

-Create a model using Tools > MS/MS intensity prediction (I used the msms_short.txt provided in a previously closed issue)
-Specify this custom model to be used by MaxDIA > Library type > Predicted > Custom
-Error on Library_prediction_0

Error
... Check failed: learner_model_param_.num_feature >= p_fmat->Info().num_col_ (216 vs. 227) : Number of columns does not match number of features in booster._ ...

Many thanks for any ideas or help with this! Are there parameters I can specify for building with the expected 227 features?

Hi! Can you attach mqpar.xml file of this run?

Cheers thanks!

I have an update to my error description:

The correct error message I receive when doing the described process is:

Prediction model not available for fragmentation type: HCD_ at MsLib.Predict.FragPredictModelCollection.GetModel(FragmentationType fragType, String[] varMods) in C:\Users\bi\source\repos\net7\net\MsLib\Predict\FragPredictModelCollection.cs:line 61__

However, I can see the metadata file in the custom model folder describes it as HCD.

The error message in my first post occurred when I replaced the files in bin/conf/fragModel/standard/unmodified/ with my custom model.

Yes, specifying a custom model folder only works if the models lie inside the same folder structure as the default ones (so you need to have standard/hcd/unmodified inside the folder you set in MQ).
Okay, I don't see anything wrong in mqpar. Did you change any parameters when training the models?

[hspekt]

No change to the parameters when training the models, although I did try with and without the default variable modifications.

When I supply the standard/hcd/unmodified file structure I get a different error:

L:\HS\xxx\combined\proc Library_prediction_0 0 Library_prediction_0 (01/16) Process 77 0 L:\HS\xxx\mqpar.xml 0 0 16_Never get here._ at MsLib.Fragment.FragmentationTypes.FromName(String fragName)

Can you try specifying standard as Custom directory? It is working for me.
I'm running now using the same MQ version and the same msms to generate library but still unable to reproduce the issue.
Did you copy the metadata file as well when copying model files to the default directory?
