Sample GSM556671 Query DataSets for GSM556671
Status Public on Sep 09, 2011
Title chimp_1
Sample type SRA
 
Source name whole blood
Organism Pan troglodytes
Characteristics cell type: neutrophil
gender: male
age: young adult
Growth protocol Whole-blod samples were obtained from healthy, young adult males.
Extracted molecule genomic DNA
Extraction protocol Neutrophils were isolated immediately after phlebotomy with CD-16 microbeads. An aliquot of each specimen was Wright-Giemsa stained and examined microscopically; all specimens contained >99% neutrophils. DNA was extracted by standard methods, and digested overnight with the methylation-sensitive enyzme HpaII (HpaII cuts CCGG sites when the central C is unmethylated). HpaII fragments of 50-300 bp in length were isolated from an agarose gel, and used to construct single read sequencing libraries using the standard Illumina protocol.
 
Library strategy MRE-Seq
Library source genomic
Library selection Restriction Digest
Instrument model Illumina Genome Analyzer
 
Description HpaII digest
Data processing Alignment ('_bwtout.txt' files): sequencing data were quality-filtered using the Illumina Pipeline CHASTITY filter with default parameter (0.6) and aligned using Bowtie v0.9.9.2 (bowtie-bio.sourceforge.net) to their respective reference genomes. Parameters used to run bowtie: --all -m 1. These parameters allow up to 2 mismatches in the first 28nt. In v 0.9.9.2, hits are "stratified" by default: if a read has 1 zero mismatch hit, and 2 1-mismatch hits, the 1 zero mismatch hit is reported when-m 1 is specified.
Determination of metylation status ('_metmap.wig' files): reads that aligned to HpaII sites (CCGG) were analyzed with MetMap (http://www.cs.berkeley.edu/~meromit/MetMap) to infer methylation states. Results are reported for each CCGG site that can generate a sequenceable fragment (ie, the fragment is of a length that can pass the size selection step during library construction). Results are expressed as the probability p(U) that the site in unmethylated, and vary between 0 (methylated site) and 1 (unmethylated site).
