# macs3\_bdgpeakcall(1)

Model-based Analysis for ChIP-Sequencing

## NAME

mac3\_bdgpeakcall - Model-based Analysis for ChIP-Sequencing

## DESCRIPTION

usage: macs3 bdgpeakcall \[-h\] **-i** IFILE \[-c CUTOFF\] \[-l MINLEN\] \[-g MAXGAP\]

- \[--cutoff-analysis\]

  \[--cutoff-analysis-max CUTOFF\_ANALYSIS\_MAX\] \[--cutoff-analysis-steps CUTOFF\_ANALYSIS\_STEPS\] \[--no-trackline\] \[--verbose VERBOSE\] \[--outdir OUTDIR\] (**-o** OFILE \| **--o-prefix** OPREFIX)

### options:

- **-h**, **--help**

  show this help message and exit

- **-i**, **--ifile** IFILE

  MACS score in bedGraph. REQUIRED

- **-c**, **--cutoff** CUTOFF

  Cutoff depends on which method you used for score track. If the file contains pvalue scores from MACS3, score 5 means pvalue 1e-5. Regions with signals lower than cutoff will not be considerred as enriched regions. DEFAULT: 5

- **-l**, **--min-length** MINLEN

  minimum length of peak, better to set it as d value. DEFAULT: 200

- **-g**, **--max-gap** MAXGAP

  maximum gap between significant points in a peak, better to set it as tag size. DEFAULT: 30

- **--cutoff-analysis**

  While set, bdgpeakcall will analyze number or total length of peaks that can be called by different cutoff then output a summary table to help user decide a better cutoff. Note, minlen and maxgap may affect the results. DEFAULT: False

- **--cutoff-analysis-max** CUTOFF\_ANALYSIS\_MAX

  The maximum cutoff score for performing cutoff analysis. Together with **--cutoff-analysis-steps**, the resolution in the final report can be controlled. Please check the description in **--cutoff-analysissteps** for detail. DEFAULT: 100

- **--cutoff-analysis-steps** CUTOFF\_ANALYSIS\_STEPS

  Steps for performing cutoff analysis. It will be used to decide which cutoff value should be included in the final report. Larger the value, higher resolution the cutoff analysis can be. The cutoff analysis function will first find the smallest (at least 0) and the largest (controlled by **--cutoff-analysis-max**) score in the data, then break the range of score into \`CUTOFF\_ANALYSIS\_STEPS\` intervals. It will then use each score as cutoff to call peaks and calculate the total number of candidate peaks, the total basepairs of peaks, and the average length of peak in basepair. Please note that the final report ideally should include \`CUTOFF\_ANALYSIS\_STEPS\` rows, but in practice, if the cutoff yield zero peak, the row for that value won't be included. DEFAULT: 100

- **--no-trackline**

  Tells MACS not to include trackline with bedGraph files. The trackline is used by UCSC for the options for display.

- **--verbose** VERBOSE

  Set verbose level of runtime message. 0: only show critical message, 1: show additional warning message, 2: show process information, 3: show debug messages. DEFAULT:2

- **--outdir** OUTDIR

  If specified all output files will be written to that directory. Default: the current working directory

- **-o**, **--ofile** OFILE

  Output file name. Mutually exclusive with **--o-prefix**.

- **--o-prefix** OPREFIX

  Output file prefix. Mutually exclusive with **-o**/--ofile.
