straw_dump

R Documentation

straw_dump

Description

Interface for Juicer's dump in case C++ straw fails (known to fail on Windows due to zlib compression not being OS agnostic and particularly not preserving null bytes, which .hic files are delimited with). This function reads the .hic file, finds the appropriate matrix and slice of data, writes it to a temp file, reads and modifies it, and outputs as an R DataFrame (and also deletes the temp file).

Usage

straw_dump(norm, fn, ch1, ch2, u, bs)

Arguments

`norm`	Normalization to apply. Must be one of NONE/VC/VC_SQRT/KR. VC is vanilla coverage, VC_SQRT is square root of vanilla coverage, and KR is Knight-Ruiz or Balanced normalization.
`fn`	path to the .hic file
`ch1`	first chromosome location (e.g., "1")
`ch2`	second chromosome location (e.g., "8")
`u`	BP (BasePair) or FRAG (restriction enzyme FRAGment)
`bs`	The bin size. By default, for BP, this is one of <2500000, 1000000, 500000, 250000, 100000, 50000, 25000, 10000, 5000> and for FRAG this is one of <500, 200, 100, 50, 20, 5, 2, 1>.
