| Title |
t2 BrdU_limit (90 min) (Nanopore) |
| Sample type |
SRA |
| |
|
| Source name |
genomic DNA from cells released into media containing 40 ug/ml BrdU for 90 min in the presenc of nocodazole
|
| Organism |
Saccharomyces cerevisiae |
| Characteristics |
strain: E3087
relevant genotype: URA3::GPD-TK(5x), AUR1c::ADH-hENT1, RAD5+
|
| 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 |
Raw nanopore sequencing reads and associated processed files
|
| 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
