 ?tags:Biocaml_wig.tag list ->
 unit ->
 (string, (Biocaml_wig.t, Biocaml_wig.parse_error) Core.Result.t)
 Biocaml_transform.t

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

val t_to_string  : ?tags:Biocaml_wig.tag list ->
 unit -> (Biocaml_wig.t, string) Biocaml_transform.t

Create the transform that prints t values to strings.

val t_to_bed_graph  : unit ->
 (Biocaml_wig.t,
 (Biocaml_wig.bed_graph_value,
 [ `not_in_fixed_step_state | `not_in_variable_step_state ])
 Core.Result.t)
 Biocaml_transform.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 _ and `comment _ values stay untouched.
