Sample GSM3450321 Query DataSets for GSM3450321
Status Public on Mar 29, 2019
Title 80% BrdU / 20% T media (control input)
Sample type SRA
 
Source name genomic DNA from cells grown in YPG media containing 100 uM of 80% BrdU and 20% thymidine for 24 hours
Organism Saccharomyces cerevisiae
Characteristics strain: YVL11
relevant genotype: MATa ADE2 cdc21::kanMX leu2::LEU2-GAL-hENT1 LYS2 RAD5 trp1::TRP1-GAL-dNK ura3-1
Extracted molecule genomic DNA
Extraction protocol Cells were harvested, spun down, washed in water, and then resuspended in 500 µL of 1.2 M sorbitol, 200 mM Tris-HCl (pH7.5), 20 mM EDTA, 0.1% b-mercaptoethanol. Cells were spheroplasted with Zymolyase and then treated with SDS, Proteinase K and RNase A. DNA was purified by phenol chloroform extraction.
Library preparation and sequencing was carried out according to Illumina and ONT instructions.

Description Illumina sequencing reads from control input sample
Data processing Illumina: sequencing reads were demultiplexed and the barcode sequences were trimmed using the FASTX toolkit
Illumina: Sequencing reads were mapped to the sacCer3 genome assembly using bowtie2
Illumina: Read tag counts were determined for the 5’ end of uniquely mapping reads without mismatches in 100 bp nonoverlapping regions
Illumina: The ratio between IP and Input sample was calculated for each bin, excluding bins that had less than 20% of the expected number of reads in the input sample
Illumina: Ratios were median-smoothed over 1 kb windows
Nanopore: Basecalling was perform with Albacore
Nanopore: Aligned reads to sacCer3 reference using minimap2
Nanopore: Detected BrdU in reads using D-NAscent
Nanopore: D-NAscent converts called BrdU sites to psl files
Nanopore: D-NAscent converts regions of called BrdU into bedgraphs
Genome_build: sacCer3
Supplementary_files_format_and_content: bed files show either BrdU-seq data or D-Nascent origin calls
Supplementary_files_format_and_content: bedgraphs show either BrdU calls or fork direction
Supplementary_files_format_and_content: psl files show hard call BrdU detectiondata
