Description

This program calculates the methylation profile (i.e., average beta value) for genomic regions around genes. These genomic regions include:

  • 5'UTR exon
  • CDS exon
  • 3'UTR exon,
  • first intron
  • internal intron
  • last intron
  • up-stream intergenic
  • down-stream intergenic

Example of input (BED6+)

chr22   44021512        44021513        cg24055475      0.9231  -
chr13   111568382       111568383       cg06540715      0.1071  +
chr20   44033594        44033595        cg21482942      0.6122  -

Options

--version show program's version number and exit -h, --help show this help message and exit -i INPUT_FILE, --input_file=INPUT_FILE BED6+ file specifying the C position. This BED file should have at least 6 columns (Chrom, ChromStart, ChromeEnd, Name, Beta_value, Strand). BED6+ file can be a regular text file or compressed file (.gz, .bz2). -r GENE_FILE, --refgene=GENE_FILE Reference gene model in standard BED12 format (https://genome.ucsc.edu/FAQ/FAQformat.html#format1). "Strand" column must exist in order to decide 5' and 3' UTRs, up- and down-stream intergenic regions. -d DOWNSTREAM_SIZE, --downstream=DOWNSTREAM_SIZE Size of down-stream genomic region added to gene. default=2000 (bp) -u UPSTREAM_SIZE, --upstream=UPSTREAM_SIZE Size of up-stream genomic region added to gene. default=2000 (bp) -o OUT_FILE, --output=OUT_FILE The prefix of the output file.

Command

$beta_profile_gene_centered.py -i test_02.bed6.gz  -r hg19.RefSeq.union.bed.gz -o gene_profile

Output files

  • gene_profile.txt
  • gene_profile.r
