Details of analyses and figures from this study are in the markdown files listed above. Additional information on data processing can be found in data type sub-directories /wgbs/analysis_scripts, RNAseq/analysis_scripts, /ChIPseq/, and /ATACseq/analysis_scrpits.
A vast majority of analyses and figures presented in this study were produced with processed WGBS data in CGmap file format that can be downloaded from GEO. These CGmap files can be used to create BSseq objects for data analysis in R.

For each sample, we generated two BSseq objects: One for CpG methylation, and another for CpA methylation using the scripts wgbs/analysis_scripts/make_BSseq_CG_context_obj.R wgbs/analysis_scripts/make_BSseq_CA_context_obj.R.

Downloading the CGmap files for WGBS data and processing with these scripts should generate .Rds files containing BSseq objects with the same naming convention in the sample metadata file wgbs/metadata/wgbs_metadata_local.csv.

This metadata file has the information required to reproduce the analyses detailed in the R markdown files in this repository.

All additional files for running the analyses in these Rmarkdown documents will be availble if you clone this repository.
