**What it does**

The IGVTools_ tile command converts a sorted data input file to a binary tiled data (.tdf) file. Use this command to pre-process large datasets for improved IGV performance.

**Input formats**

Supported input file formats are: .wig, .cn, .snp, .igv, and .gct.

------

**Outputs**

The output format is IGV tiled data file (TDF) file (.tdf)

**IGVTools count  parameter list**

This is an exhaustive list of igvtools count options:

For **count**::

  -z Integer        Specifies the maximum zoom level to precompute. The default
                    value is 7 and is sufficient for most files. To reduce file
                    size at the expense of IGV performance this value can be
                    reduced.
  
  -p file           Specifies a "bed" file to be used to map probe identifiers
                    to locations.  This option is useful when preprocessing . gct
                    files.  The bed file should contain 4 columns:
                    chr start end name
                    where name is the probe name in the .gct file.
  
  -f list           A comma delimited list specifying window functions to use
                    when reducing the data to precomputed tiles.   Possible
                    values are  min, max, and mean.  By default only the mean
                    is calculated.
