Extract reads from reference
############################

Extract sequencing-like reads from a reference database.

Parameters
----------
sequences : FeatureData[Sequence]
	\

f_primer : Str
    forward primer sequence
r_primer : Str
    reverse primer sequence
trunc_len : Int, optional
    read is cut to trunc_len if trunc_len is positive. Applied before
    trim_left.
trim_left : Int, optional
    trim_left nucleotides are removed from the 5' end if trim_left is
    positive. Applied after trunc_len.
identity : Float, optional
    minimum combined primer match identity threshold.
min_length : Int % Range(0, None), optional
    Minimum amplicon length. Shorter amplicons are discarded. Applied after
    trimming and truncation, so be aware that trimming may impact sequence
    retention. Set to zero to disable min length filtering.
max_length : Int % Range(0, None), optional
    Maximum amplicon length. Longer amplicons are discarded. Applied before
    trimming and truncation, so plan accordingly. Set to zero (default) to
    disable max length filtering.

Returns
-------
