Q1. Is there dataset of transcription start sites collected with only noncording RNA regions?

• A1. Currently, there are no data that collects only the transcription start sites of non-coding RNAs. It is possible to extract noncording RNAs by concatenating the GENCODE annotation file and the following files:

Q2. Why the range of some TSSs are so much greater than others? For most TSSs the range is in the region of 8-24 bp, while for others the range is over 100 bp.

• A2. The range of TSSs is in the region of 8-24 bp, while for others the range can be over 100 bp. We computationally identify TSS regions based on the mapping results with 5'-end sequences.
