HiContactsData is a companion data package giving programmatic access to
several processed Hi-C files for demonstration, such as cool, mcool and
pairs files. It is meant to be used with HiContacts.
library(HiContactsData)The only function provided by HiContactsData package is HiContactsData().
Several files are avaible using this function, namely:
sample: yeast_wt, format = fastq_R{12})sample: yeast_wt, format = HiCool_log)sample: yeast_wt, format = cool)sample: yeast_wt, format = mcool)sample: yeast_wt, format = hic)sample: yeast_wt, format = hicpro_matrix)sample: yeast_wt, format = hicpro_bed)sample: yeast_wt, format = pairs)sample: yeast_Eco1, format = mcool)sample: yeast_Eco1, format = pairs)sample: mESCs, format = mcool)sample: mESCs, format = pairs)Yeast data comes from Bastie, Chapard et al., Nature Structural & Molecular Biology 2022 and mouse ESC data comes from Bonev et al., Cell 2017.
To download one of these files, one can specify a sample and a file format:
cool_file <- HiContactsData()
