Morphology Function Framework

This repository links whole-slide-image (WSI) morphology to molecular function and patient survival. It is organized as five sub-projects that run in sequence (with one branch running in parallel), each documented independently with its own README.md and USAGE.md. This top-level document explains how the five sub-projects fit together, what data flows between them, and where to find detailed instructions.

Two branches converging on one joint model

The framework has a Morphology branch (image -> WSI-to-RNA) and a Function branch (molecular data -> Functional Extraction Module -> survival model). Both branches are trained independently, and the demo project is the joint inference stage that combines their outputs.

text

Morphology branch (WSI):
  image_preprocess -> compute_uni_features -> src_wsi2rna_model

Function branch (molecular / GO):
  src_surv_model (GeneExpression / CNA / RPPA)

Joint inference (uses checkpoints and resources from both branches):
  demo

Sub-project summary and data flow

Order	Sub-project	Reads	Produces	Docs
1	`image_preprocess`	raw TCGA WSIs, gene-expression matrix	`data/40x_grouped_with_gene_expression/<SAMPLE_ID>/wsi/*.png` + `gene_expression.csv`	README / USAGE
2	`compute_uni_features`	output of step 1	`data/Patches_hdf5`, `data/uni_features/<PROJECT>/<SLIDE_ID>/<SLIDE_ID>.h5` (dataset `cluster_features`)	README / USAGE
3	`src_wsi2rna_model`	`cluster_features` from step 2	trained checkpoints under `log/<cohort>/<exp_name>/model_best*.pt`	README / USAGE
—	`src_surv_model`	raw GeneExpression / CNA / RPPA + GO ontology resources (independent of steps 1-3)	FEM resources (`FEM_files/<MODAL>/files/`) + trained survival checkpoints under `model/log/`	README / USAGE
4	`demo`	UNI features (step 2) + WSI2RNA checkpoints (step 3) + FEM resources and a survival checkpoint (from `src_surv_model`)	`pipeline_results/` predictions, GO scores, GO-occlusion results, R figures	README / USAGE

Only demo reads from more than one sub-project at once; every other sub-project reads only the single upstream directory named in the table above. See USAGE.md for the exact directory layout expected between projects and every runnable command.

Data download

Raw TCGA WSIs, gene-expression/CNA/RPPA matrices, clinical/survival tables, generated patches, UNI features, GO ontology resources, and trained checkpoints are not distributed with this repository. Each sub-project's USAGE.md documents exactly which files must be placed under which path before its scripts can run, and which resources (e.g. the UNI checkpoint, the ViS checkpoint, go-basic.obo) can be downloaded automatically when network access is available.

Evaluation

Quantitative evaluation (C-index, time-dependent AUC/ROC, True GE vs. Simulated-GE agreement, GO high/low group comparisons, and GO-occlusion relevance to survival risk) is produced by src_wsi2rna_model (WSI2RNA metrics), src_surv_model (five-fold CV and hold-out survival metrics, model/figure_script.R), and demo (joint hold-out evaluation and figure_script.R). See each project's USAGE.md for the exact output files.

Getting started

See USAGE.md for a full, ordered, end-to-end walkthrough (environment setup, required input files, exact commands, and expected outputs for every sub-project).

Data and code availability

Raw patient-level data (WSIs, molecular matrices, clinical/survival tables) and trained checkpoints are not included in this repository. Obtain and use them under their applicable access, privacy, and redistribution conditions. Each sub-project ships a .gitignore that excludes these paths by default.
