# macs2\_predictd(1)

Model-based Analysis for ChIP-Sequencing

## NAME

macs2\_predictd - Model-based Analysis for ChIP-Sequencing

## DESCRIPTION

usage: macs2 predictd \[-h\] **-i** IFILE \[IFILE ...\]

- \[-f {AUTO,BAM,SAM,BED,ELAND,ELANDMULTI,ELANDEXPORT,BOWTIE,BAMPE,BEDPE}\]

  \[-g GSIZE\] \[-s TSIZE\] \[--bw BW\] \[--d-min D\_MIN\] \[-m MFOLD MFOLD\] \[--outdir OUTDIR\] \[--rfile RFILE\] \[--buffer-size BUFFER\_SIZE\] \[--verbose VERBOSE\]

### options:

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

  show this help message and exit

- **-i** IFILE \[IFILE ...\], **--ifile** IFILE \[IFILE ...\]

  ChIP-seq alignment file. If multiple files are given as '-t A B C', then they will all be read and combined. Note that pair-end data is not supposed to work with this command. REQUIRED.

- **-f** {AUTO,BAM,SAM,BED,ELAND,ELANDMULTI,ELANDEXPORT,BOWTIE,BAMPE,BEDPE}, **--format** {AUTO,BAM,SAM,BED,ELAND,ELANDMULTI,ELANDEXPORT,BOWTIE,BAMPE,BEDPE}

  Format of tag file, "AUTO", "BED" or "ELAND" or "ELANDMULTI" or "ELANDEXPORT" or "SAM" or "BAM" or "BOWTIE" or "BAMPE" or "BEDPE". The default AUTO option will let MACS decide which format the file is. Please check the definition in README file if you choose ELAND/ELANDMULTI/ELANDEXPORT/SAM/BAM/BOWTIE. DEFAULT: "AUTO"

- **-g** GSIZE, **--gsize** GSIZE

  Effective genome size. It can be 1.0e+9 or 1000000000, or shortcuts:'hs' for human (2.7e9), 'mm' for mouse (1.87e9), 'ce' for C. elegans (9e7) and 'dm' for fruitfly (1.2e8), Default:hs

- **-s** TSIZE, **--tsize** TSIZE

  Tag size. This will override the auto detected tag size. DEFAULT: Not set

- **--bw** BW

  Band width for picking regions to compute fragment size. This value is only used while building the shifting model. DEFAULT: 300

- **--d-min** D\_MIN

  Minimum fragment size in basepair. Any predicted fragment size less than this will be excluded. DEFAULT: 20

- **-m** MFOLD MFOLD, **--mfold** MFOLD MFOLD

  Select the regions within MFOLD range of highconfidence enrichment ratio against background to build model. Fold-enrichment in regions must be lower than upper limit, and higher than the lower limit. Use as "-m 10 30". DEFAULT:5 50

- **--outdir** OUTDIR

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

- **--rfile** RFILE

  PREFIX of filename of R script for drawing X-correlation figure. DEFAULT:'predictd' and R file will be predicted\_model.R

- **--buffer-size** BUFFER\_SIZE

  Buffer size for incrementally increasing internal array size to store reads alignment information. In most cases, you don't have to change this parameter. However, if there are large number of chromosomes/contigs/scaffolds in your alignment, it's recommended to specify a smaller buffer size in order to decrease memory usage (but it will take longer time to read alignment files). Minimum memory requested for reading an alignment file is about # of CHROMOSOME \* BUFFER\_SIZE \* 8 Bytes. DEFAULT: 100000

- **--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
