title: Illumina NovaSeq 6000 paired end sequencing; Promoter Capture Hi-C on hindlimb muscle cells from one-day old chick. Promoter Capture Hi-C data was generated to support annotation of regulatory elements of coding and non-coding genes and to evaluate the tissue-specificity of such regulaory elements. This study is part of GENE-SWitCH and the FAANG project, promoting rapid prepublication of data to support the research community. These data are released under Fort Lauderdale principles, as confirmed in the Toronto Statement (Toronto International Data Release Workshop. Birney et al. 2009. Pre-publication data sharing. Nature 461:168-170). Any use of this dataset must abide by the FAANG data sharing principles. Data producers reserve the right to make the first publication of a global analysis of this data. If you are unsure if you are allowed to publish on this dataset, please contact the FAANG Data Coordination Centre and FAANG Consortium (email faang-dcc@ebi.ac.uk and copy faang@iastate.edu) to enquire.
