- Bioinformatics
- Align reads the human genome (hg38) using bowtie78 with settings -X 700 -m1 -v 3. Remove duplicate reads, and sort files using samtools. Filter mapped reads for size, keeping only reads with a fragment size at or below 120 base pairs.
- Generate bedgraph files using bedtools genomecov.
- Call peaks using SEACR version 1.3, in relaxed mode, normalizing to the negative control.

- 背景
- This gene encodes a zinc finger transcription factor thought to play a role in the development of abducens motor neurons. Defects in this gene are a cause of Duane-radial ray syndrome (DRRS). Alternative splicing results in multiple transcript variants encoding different isoforms.,SALL4,DRRS,HSAL4,ZNF797,Epigenetics & Nuclear Signaling,Cell Biology & Developmental Biology,Stem Cells,Embryonic Stem Cells,SALL4
