## parseCAGEscanBlocksToGrangeTSS

### Description

Parse a string describing a block in a CAGEscan molecule, as output by the "CAGEscan 3.0" pipeline.

### Usage

    parseCAGEscanBlocksToGrangeTSS(blocks)

### Arguments

`blocks` | A character string representing a block in a CAGEscan molecule.

### Value

A GRanges object representing a TSS.

In CAGEscan molecules, blocks are separated by ‘|’, ‘,’ or ‘;’ for gap of coverage, splice junction (confident) and splice junction (maybe) respectively. Strand is "+" if first coordinate is lower than the second one, and "-" otherwise.
