Ercan11, Nucleosome occupancy profiling by high throughput sequencing


Nucleosome occupancy profiles of different developmental stages in C. elegans: embryos, germlineless adults, germ line containing adults, and XO hermaphrodites at L3 larval stage. A control sample is also present.


Data can be downloaded from: GEO dataset GSE20136


From C. elegans genome WC190 (ce6).

Technical Notes

SRA files were downloaded from GEO GSE20136 and converted in FASTQ using fastq-dump program from sratoolkit. Mapping was done using Bowtie and sam files were converted in sga files using samtools and chipseq.
