Module Wig.Transform

Low-level Tfxm.t.

val string_to_item : ?filename:string -> ?tags:Tags.t -> unit -> (string, (item, [> Error.parsing ]) Core_kernel.result) Tfxm.t

Create the parsing Tfxm.t. The parser is "best-effort" and stateless (i.e. a line containing "1000 42." will parsed successfully as a `variable_step_value (1000, 42.) even if no "variableStep" was line present before).

val item_to_string : ?tags:Tags.t -> unit -> (item, string) Tfxm.t

Create the transform that prints item values to strings.

val item_to_bed_graph : unit -> (item, (bed_graph_value, [> Error.to_bed_graph ]) Core_kernel.result) Tfxm.t

Create a transform which converts `variable_step_value _ and `fixed_step_value _ values to `bed_graph_value _ values, using the current state. The `bed_graph_value _ items stay untouched and `comment _ values are ignored.
