Sample GSM1637798 Query DataSets for GSM1637798
Status Public on May 05, 2015
Title SMRT-sequencing
Sample type SRA
 
Source name whole worm WT gDNA
Organism Caenorhabditis elegans
Characteristics developmental stage: WT (N2) mixed stage worms
Treatment protocol Worms were fed dam-dcm- bacteria
Growth protocol Mixed stage WT (N2) worms were grown at 20 degrees
Extracted molecule genomic DNA
Extraction protocol Worms were washed several times with M9 buffer and snap frozen in liquid nitrogen. Pellets were sent to Umass Medical School Deep Sequencing Core for gDNA extraction and SMRT sequencing
Library was constructed by Umass Medical School Deep sequencing core. Single Molecule Real Time Sequencing
 
Library strategy OTHER
Library source genomic
Library selection other
Instrument model PacBio RS II
 
Data processing mapping using pbalign
The polymerase kinetics information was further loaded after alignment by loadChemistry.py and loadPulses scripts
post-aligned datasets were merged and sorted by using cmph5tools
m6A was identified using ipdSummary.py
Genome_build: ce10
m6A.gff
column: description
chr: chrromosome name
source: Name of tool -- "kinModCall"
type: Modification type -- a generic tag "modified_base" is used for unidentified bases. For identified bases, m6A, m4C, and m5C are used
start: start
end: end
score: -10 log (p-value) score for the detection of this event. Analogous to a Phred quality score. A value of 20 is the minimum default threshold for this file, and corresponds to a p-value of 0.01. A score of 30 corresponds to a pvalue of 0.001.
strand: Native sample strand where kinetics were generated. "+" is the strand of the original FASTA and "-" is the reverse complement of the strand. Note that in the .csv file these are marked "0" and "1" respectively.
phase: Not applicable
attibutes: Contains extra fields. IPDRatio is traditional IPD Ratio, context is the reference sequence -20bp to +20bp around the modification plus the base at this location as the 21st character, and sequencing coverage of that position. Context is always written in 5" -> 3" orientation of the template strand.
