Installation

Create and activate a conda environment and install the required packages:

conda create -p /env_path/BioM3_env python=3.10 # /env_path/ is the location that contains the conda env
conda activate /env_path/BioM3_env

Stage 1: PenCL Inference

Overview

This stage demonstrates how to perform inference using the BioM3 PenCL model for aligning protein sequences and text descriptions. The model computes latent embeddings for the given inputs and calculates dot product scores (similarities) with normalization.

Model Weights

Before running the model, ensure you have:

  • Configuration file: stage1_config.json
  • Pre-trained weights: BioM3_PenCL_epoch20.bin, esm2_t33_650M_UR50D.pt, esm2_t33_650M_UR50D-contact-regression.pt, and BiomedNLP-BiomedBERT-base-uncased-abstract-fulltext.

Running the Model

  1. Change json configuration for Stage 1:
vim stage1_config.json

# replace <working_directory> with your path
"seq_model_path": "<working_directory>/BioM3/weights/LLMs/esm2_t33_650M_UR50D.pt"
"text_model_path": "<working_directory>/weights/LLMs/BiomedNLP-BiomedBERT-base-uncased-abstract-fulltext",
  1. Change directory to BioM3 repo:
cd /path/BioM3 # /path/ where is the location to the cloned BioM3 repo
  1. Run inference:
python run_PenCL_inference.py \
    --json_path "stage1_config.json" \
    --model_path "./weights/PenCL/BioM3_PenCL_epoch20.bin" \
    --output_path "test_PenCL_embeddings.pt"

Example Input Data

The script demonstrates inference using two protein-text pairs from the SwissProt dataset:

Pair 1:

  • Protein Sequence: MAKEDNIEMQGTVLETLPNTMFRVELENGHVVTAHISGKMRKNYIRILTGDKVTVELTPYDLSKGRIVFRSR
  • Text Description: PROTEIN NAME: Translation initiation factor IF-1. FUNCTION: One of the essential components for the initiation of protein synthesis. Binds in the vicinity of the A-site. Stabilizes the binding of IF-2 and IF-3 on the 30S subunit to which N-formylmethionyl-tRNA(fMet) subsequently binds. Helps modulate mRNA selection, yielding the 30S pre-initiation complex (PIC). Upon addition of the 50S ribosomal subunit, IF-1, IF-2 and IF-3 are released leaving the mature 70S translation initiation complex. SUBUNIT: Component of the 30S ribosomal translation pre-initiation complex which assembles on the 30S ribosome in the order IF-2 and IF-3, IF-1 and N-formylmethionyl-tRNA(fMet); mRNA recruitment can occur at any time during PIC assembly. SUBCELLULAR LOCATION: Cytoplasm. SIMILARITY: Belongs to the IF-1 family.

Stage 2: Facilitator Sampling

Overview

In this stage, the Facilitator model takes the text embeddings (z_t) computed in Stage 1 and generates facilitated embeddings (z_c). The facilitated embeddings align more closely with protein embeddings (z_p) and reduce discrepancies, as demonstrated by Mean Squared Error (MSE) and Maximum Mean Discrepancy (MMD) metrics.

Model Weights

Before running the model, ensure you have:

  • Configuration file: stage2_facilitator_config.json
  • Pre-trained weights: BioM3_Facilitator_epoch20.bin

Running the Facilitator Model

  1. Run sampling:
python run_Facilitator_sample.py \
    --json_path "stage2_config.json" \
    --model_path "./weights/Facilitator/BioM3_Facilitator_epoch20.bin" \
    --input_data_path "test_PenCL_embeddings.pt" \
    --output_data_path "test_Facilitator_embeddings.pt"

Arguments:

  • json_path: Path to the JSON configuration file
  • model_path: Path to the pre-trained facilitator weights
  • input_data_path: Path to the input embeddings (z_t and z_p) generated in Stage 1
  • output_data_path: Path to save the facilitated embeddings (z_c)

Expected Output

The script provides the following outputs:

  1. Latent Embedding Shapes

    • z_t: Text embeddings
    • z_p: Protein embeddings
    • z_c: Facilitated embeddings

  2. Vector Magnitudes

    • L2 norms of z_t, z_p, and z_c for a given batch

  3. Mean Squared Error (MSE)

    • MSE between facilitated embeddings (z_c) and protein embeddings (z_p)
    • MSE between text embeddings (z_t) and protein embeddings (z_p)

  4. Maximum Mean Discrepancy (MMD)

    • MMD between facilitated embeddings (z_c) and protein embeddings (z_p)
    • MMD between text embeddings (z_t) and protein embeddings (z_p)

Sample Output 

=== Facilitator Model Output ===
Shape of z_t (Text Embeddings): torch.Size([5, 512])
Shape of z_p (Protein Embeddings): torch.Size([5, 512])
Shape of z_c (Facilitated Embeddings): torch.Size([5, 512])

=== Norm (L2 Magnitude) Results for Batch Index 0 ===
Norm of z_t (Text Embedding): 33.364857
Norm of z_p (Protein Embedding): 4.289446
Norm of z_c (Facilitated Embedding): 3.976427

=== Mean Squared Error (MSE) Results ===
MSE between Facilitated Embeddings (z_c) and Protein Embeddings (z_p): 0.013486
MSE between Text Embeddings (z_t) and Protein Embeddings (z_p): 1.937837

=== Max Mean Discrepancy (MMD) Results ===
MMD between Facilitated Embeddings (z_c) and Protein Embeddings (z_p): 0.000009
MMD between Text Embeddings (z_t) and Protein Embeddings (z_p): 0.004736

What the Output Means

  1. Latent Shapes:

    • Ensures that z_c has the same shape as z_p and z_t

  2. Norms:

    • z_c is closer in magnitude to z_p compared to z_t, showing that the facilitator model effectively aligns the embeddings

  3. MSE:

    • Lower MSE for z_c and z_p compared to z_t and z_p confirms that z_c approximates z_p better

  4. MMD:

    • The MMD loss shows that the distribution of z_c is closer to z_p than the original z_t

Saving the Output

The facilitated embeddings are saved to the specified output_data_path for further stages.

Stage 3: ProteoScribe

Overview

In this stage, the ProteoScribe model takes the facilitated embeddings (z_c) from Stage 2 and generates novel protein sequences that match the desired functional description. The model outputs multiple sequence variants (replicas) for each input embedding.

python run_ProteoScribe_sample.py \
    --json_path "./stage3_config.json" \
    --model_path "./weights/ProteoScribe/BioM3_ProteoScribe_pfam_epoch20_v1.bin" \
    --input_path "test_Facilitator_embeddings.pt" \
    --output_path "test_ProteoScribe_samples.pt"
