setIntervalScale: Set x and y interval of the HTCexp object
In HiTC: High Throughput Chromosome Conformation Capture analysis

Description Usage Arguments Details Value Author(s) See Also Examples

Set x and y interval of the HTCexp object and update the contact map accordingly

1 2	setIntervalScale(x, xgi, ygi, upa=TRUE, method=c("sum","median","mean"), use.zero=TRUE, optimize.by = c("speed", "memory"))

`x`	object that inherits from class `HTCexp`
`ygi`	y intervals; see class `GRanges` for details
`xgi`	x intervals; see class `GRanges` for details
`upa`	logical; unique primer assignment. Allow one primer to belong to one or several bins
`method`	the method used to combine the counts. Must be ‘mean’, ‘median’ or ‘sum’
`use.zero`	logical; use the zero values in the `method` calculation
`optimize.by`	"speed" will use faster methods but more RAM, and "memory" will be slower, but require less RAM

Define new contact map based on the specified xgi and ygi intervals.

This function has to be used carefully and can has important impact on the contact map. It is important to note that the setIntervalScale function is different from the binningC function in the way that the output is not symetrical.

A HTCexp object

HTCexp-class

data(Nora_5C)

E14.bin<-binningC(E14$chrXchrX)

## I have two HTCexp samples defined with different intervals.
show(E14.bin)
show(MEF$chrXchrX)

## How to compare them ?
## One idea is to force the intervals definition of one object using the
## intervals of the other.

setIntervalScale(MEF$chrXchrX, xgi=x_intervals(E14.bin), ygi=y_intervals(E14.bin))
