 pretty_name: MIRROR Pruned TCGA RNASeq Data
----
+---
+
+Here we provide pruned TCGA transcriptomics data from manuscript "[MIRROR: Multi-Modal Pathological Self-Supervised Representation Learning via Modality Alignment and Retention](https://arxiv.org/abs/2503.00374)". Code is available at [GitHub](https://github.com/TianyiFranklinWang/MIRROR).
+
+The TCGA [1] transcriptomics data were collected from Xena [2] and preprocessed using the proposed novel pipeline in MIRROR [3].
+
+For raw transcriptomics data, we first apply RFE [4] with 5-fold cross-validation for each cohort to identify the most performant support set for the subtyping task. To enhance interpretability from a biological perspective, we manually incorporate genes associated with specific cancer subtypes based on the COSMIC database [5], resulting in a one-dimensional transcriptomics feature vector.
