latest version of DANPOS DANPOS311 June 2020 the 311 version Updated from DANPOS2 to run with updated packages Python 376 R 401 samtools 17 htslib 17 Thanks to Samantha Klasfeld from the Wagner lab at the University of Pennsylvania for contributing to the Jan 2 2013 DANPOS can distinguish functional categories of nucleosomes Even though the sequencing depth was 200fold they were still finding more dynamic nucleosomes with greater sequencing depth In human hematopoietic stem cells and mouse embryonic stem cells DANPOS found dynamic nucleosomes in promoters and in distal regions DANPOS on Biowulf National Institutes of Health DANPOS dynamic analysis of nucleosome position and occupancy Mar 30 2021 Here we report a comprehensive bioinformatics pipeline DANPOS explicitly designed for dynamic nucleosome analysis at singlenucleotide resolution Using both simulated and real nucleosome data we demonstrated that bias correction in preliminary data processing and optimal statistical testing

different manner dpos analyzes changes in the location fuzziness and occupancy at each nucleosome or protein binding position The functions is designed to analyze nucleosomes but can be also very useful for analyzing other proteins whose binding pattern is similar to that of Jun 15 2020 A bug in setting the step size bataviaslot for pairedend reads input has been corrected in the new release

detect all three categories of nucleosome dynamics such as position shift fuzziness change and occupancy change using a uniform statistical framework Pathway analysis indicates that each category is involved in distinct biological functions DANPOS Dynamic analysis of nucleosome position and occupancy Dec 19 2012 comparable DANPOS provides several normalization options in
