 ### Poly(A) tail estimation
 
-Dorado has experimental support for estimating poly(A) tail lengths for DNA and RNA. Note that Oxford Nanopore cDNA reads sequence in two different orientations and transcript poly(A) length estimation handles both (A and T homopolymers). This feature can be enabled by passing `--estimate-poly-a` to the `basecaller` command. It is disabled by default. The estimated tail length is stored in the `pt:i` tag of the output record. Reads for which the tail length could not be estimated will not have the `pt:i` tag.
