+# Methylation-classification Dataset
+
+## Dataset Description
+
+- **Homepage:** https://github.com/ylaboratory/methylation-classification
+- **Pubmed:** False
+- **Public:** True
+
+Methylation classification is a pan-tissue dataset and analysis paper from publicaly available DNA methylation microarrays (450K) from the Gene Expression Omnibus. The uploaded dataset of 16,959 samples encompasss 86 tissue and cell types.
+
+## Data and usage
+
+Analysis code, annotation, data files, and skeleton preprocessing code (if running starting from raw files) are located in this repo and [github](https://github.com/ylaboratory/methylation-classification).  
+  
+mvalues files contain methylation M-values preprocessed and quality controlled using minfi and wateRmelon:  
+- background corrected using [preprocessNoob](https://rdrr.io/bioc/minfi/man/preprocessNoob.html)
+- normalized using [BMIQ](https://rdrr.io/bioc/wateRmelon/man/BMIQ.html)
+
+meta files contain the following:  
+- Sample ID
+- training.ID: UBERON ID used for training (physiologically similar IDs merged, few tissues labeled as system-level node to aid in training)
+- Dataset: GSE study ID
+- Annotated.tissue: initially annotated tissue  
+- UBERON.ID: annotated tissue's most descriptive UBERON ID  
+- merged.ID: UBERON IDs after merging physiologically similar IDs
